This engineer could have just stuck with the Gateway 2000-branded, Altec Lansing-designed powered speaker set long plugged into his laptop’s headphone jack. But where’s the fun in that?

Having editorially teased my recent home office audio system upgrade several times now, beginning back in mid-August and repeatedly accompanied by promises to share full details “soon”, I figured I’d better get to writing “now” before I ended up with a reader riot on my hands. Let’s start with the “stack” to the right of my laptop, a photo of which I’ve shared before:

The unbalanced (i.e., single-ended) setup

At the bottom is a Schiit Modi Multibit 1 DAC, my teardown of which was published just last month:

Above it is Schiit’s first-generation Loki Mini four-band equalizer (versus the second-generation Loki Mini+ successor shown below, which looks identical from the outside save for altered verbiage on the back panel sticker). I decided to include it versus relying solely on software EQ since I intended to use the setup to listen to more than just computer-based audio sources.

Above it is a passive (unpowered) switch, the Schiit Sys, that enables me to select between two inputs prior to routing the audio to the Rekkr power amplifier set connected to the speakers:

And at the very top is a Schiit Vali 2++ (PDF) tube-based headphone amplifier, identical to the Vali 2+ precursor (introduced in 2000 and shown below) save for a supply constraint-compelled transition to a different tube family:

And the rack? It’s a stacked combo of two (to give me the necessary number of shelves) Topping Acrylic Racks, available both directly from the China-based manufacturer (mind the tariffs!) and from retailers such as Apos in the United States. A little pricey ($39 each), but it makes me smile every time I look at it, which is priceless…or at least that’s how I rationalized the purchase!

Audio sources and interconnects

As you’ve likely already noticed, this setup uses mainstream unbalanced (i.e., single-ended) RCA cabling. To detail the inter-device connections, let’s start with the device at the end of the chain, the Sys switch. I didn’t initially include it in the stack but then realized I didn’t want to have to turn on the Vali 2++ each time I wanted to listen to music over the speakers (whenever the headphone jack isn’t in use, the Vali 2++ passes input audio directly through to its back panel outputs), given that tubes have limited operating life and replacements are challenging at best to source. As such, while one Sys input set comes from the Vali 2++, the other is directly sourced from the analog “headphone jack” audio output built into my docking station, which is tethered to the laptop (an Intel-based 2020 13” Apple MacBook Pro) over a Thunderbolt 3 connection:

Headphone outputs have passably comparable power specs to the line-level outputs that would normally connect to the Sys switch inputs (and from there to an audio power amplifier’s inputs), with two key qualifiers:

• They’re intended to drive comparatively low-impedance headphones, not high-impedance audio inputs, and
• Given that they integrate a modest audio amplifier circuit, you need to be restrained in your use of the volume setting controlling that audio amplifier to avoid overdriving whatever non-headphone input set they’re connected to in this alternative case.

The only other downside is that since the Sys is at the end of the chain, audio sourced from the docking station’s headphone jack also bypasses the Loki Mini’s hardware EQ facilities, although since it’s always computer-originated in this particular situation, software-based tone controls such those built into Rogue Amoeba’s SoundSource utility for Macs or the open-source Equalizer EPO for Windows systems can provide a passable substitute.

Speaking of EQ, and working backwards in the chain, the Vali 2++ audio inputs are connected to the Loki Mini equalizer outputs, and the Loki Mini inputs are connected to the Modi Multibit 1 DAC outputs. And what of the DAC’s inputs? There are three available possibilities, one of which (optical S/PDIF) is currently unused.

It’s a shame that Apple phased out integrated optical S/PDIF output facilities after 2016; otherwise, I’d use them to tether the DAC to the 2018 Intel-based Apple Mac mini to the right of this stack. Unsurprisingly to you, likely, the USB input is also connected to the laptop, again via the Thunderbolt 3 docking station intermediary (albeit digitally this time). And what about the DAC’s coaxial (RCA) digital input? I’ll save that for part two next time.

The balanced alternative

Now, let’s look to the left of the laptop:

You’ve actually already seen one of the three members of this particular stack a couple of times before, albeit in a dustier and generally more disorganized fashion:

It’s now tidied up with an even pricier ($219) multi-shelf (and aluminum-based this time) rack, the Topping SR2 (here again are manufacturer and retail-partner links):

As before, the headphone amplifier is still the Drop + THX AAA 789:

But I’ve subsequently swapped out Topping’s D10 Balanced DAC:

for a Drop + Grace Design Standard DAC Balanced to assemble a Drop-branded duo:

The Topping D10 Balanced DAC is back in storage for now; I plan to eventually pair it with a S.M.S.L. SO200 THX AAA-888 Balanced Headphone Amplifier (yes, it really is slanted in shape):

And yes, I realize how abundantly blessed I am to have access to all this audio tech toy excess!

As you’ve likely already ascertained from the images (and if not that, the “Balanced” portion of the second product’s name), this particular setup instead leverages balanced interconnect, both XLR- and TRS-implemented. As such, I couldn’t merge another Schiit Loki Mini or Mini+ equalizer into the mix. Instead, I went with the balanced, six-band Schiit Lokius bigger sibling:

The Lokius EQ sits between the DAC and the headphone amplifier. The DAC’s USB input can connect to one of several nearby computers. On the one hand, this is convenient because the DAC is self-powered by that same USB connection. On the other, I’ve noticed that it sometimes picks up audible albeit low-level interference from the USB outputs of my Microsoft Surface Pro 7+ laptop (that said, no such similar issues exist with my Apple M2 Pro Mac Studio).

And what of the DAC’s optical S/PDIF input? Again, you’ll need to wait until next time for the reveal. Finally, in this case, the headphone amplifier doesn’t have pass-through outputs for direct connection to a stereo power amplifier (or, in this case, monoblock pair), so I’m instead (again, sparingly) leveraging its unbalanced headphone output.

The rest of the story

So far, we’ve covered the two stacks’ details. But what does each’s remaining S/PDIF DAC input connect to? And to what do they connect on the output end, and how? Stay tuned for part 2 to come next for the answers to these questions, along with other coverage topics. And until then, please share your so-far thoughts with your fellow readers and me in the comments!

Anritsu and VTT Technical Research Centre of Finland have demonstrated a major advance in D-band wireless communications by validating a beam-steering transmit array antenna system using advanced test equipment. The achievement confirms the feasibility of stable, high-capacity wireless links for next-generation backhaul, industrial, defence and future 6G networks.

Using Anritsu’s precision test equipment and VTT’s steerable transmitarray antenna, the teams achieved high-speed wireless links across the 110–170 GHz D-band. Link performance and beam-steering behaviour were assessed under realistic over-the-air (OTA) conditions using wideband modulated signals up to 8 GHz bandwidth. This system-level characterisation, from signal generation to OTA performance, confirmed multi-gigabit data rates in the tens-of-Gbps range, including 20 Gbps over 1 m and reliable operation up to 7 m, setting a new benchmark for D-band connectivity.

The demonstration features a lightweight, scalable transmitarray antenna developed by VTT, incorporating advanced phase-shifting elements and vector-modulator MMICs. Its electronically steerable design provides rapid, precise beam control without mechanical movement, maintaining signal strength under changing conditions. Supported by Anritsu’s state-of-the-art test equipment, the results reflect a proven, instrumentation-grade measurement approach that ensures reliability and scalability for future deployments.

“Anritsu is proud to collaborate with VTT to advance the practical use of D-band wireless technology. Together, we have validated performance levels that bring high-frequency wireless links closer to real-world deployment,” said Jonathan Borrill, CTO, Test & Measurement, Anritsu.

In electronic product design, the smallest components often have the biggest impact on system reliability. Tactile switches—used in control panels, wearables, medical devices, instrumentation, and industrial automation—are a prime example. These compact electromechanical devices must deliver a precise tactile response, stable contact resistance, and long service life despite millions of actuations and a wide range of operating conditions.

For design engineers, one of the most critical choices influencing tactile switch reliability is contact plating. Among available materials, gold plating offers unmatched advantages in conductivity, corrosion resistance, and mechanical stability. While its cost is higher than silver plating—and tin when used for terminal finishes—gold’s performance characteristics make it indispensable for mission-critical applications in which failure is not an option.

Understanding the role of plating in switch performance

The function of a tactile switch relies on momentary metal-to-metal contact closure. Over-repeated actuation, environmental exposure and mechanical wear can increase contact resistance or even lead to intermittent operation. Plating serves as a barrier layer, protecting the base metal (often copper, brass, or stainless steel) from corrosion and wear while also influencing the switch’s electrical behavior.

Different plating materials exhibit markedly different behaviors:

• Tin (used only for terminal plating) offers low cost and good solderability but oxidizes quickly, raising contact resistance in low-current circuits.
• Silver provides excellent conductivity, but it tarnishes in the presence of sulfur or humidity, forming insulating silver sulfide films.
• Gold, though softer and more expensive, is chemically inert and does not oxidize or tarnish. It maintains stable, low contact resistance even under micro-ampere currents where other metals fail.

This property is crucial for tactile switches used in low-level signal applications, such as microcontroller input circuits, communication modules, or medical sensors, in which switching currents may be in the microamp to milliamp range. At such levels, even a thin oxide film can impede electron flow, creating unreliable or noisy signals.

The science behind gold’s stability

Gold’s chemical stability stems from its electronic configuration: Its filled d-orbitals make it resistant to oxidation and most chemical reactions. Its noble nature prevents formation of insulating oxides or sulfides, meaning the surface remains metallic and conductive throughout the switch’s service life.

From a materials engineering standpoint, plating thickness and uniformity are key. Gold layers used in tactile switches typically range from 0.1 to 1.0 µm, depending on required durability and environmental conditions. Thicker plating layers provide greater wear resistance but increase cost. Engineers should verify that the plating process, often electrolytic or autocatalytic, ensures full coverage on complex contact geometries to avoid thin spots that could expose the base metal.

Many switch manufacturers, such as C&K Switches, use gold-over-nickel systems. The nickel layer acts as a diffusion barrier, preventing copper migration into the gold and preserving long-term contact integrity. Without this barrier, copper atoms could diffuse to the surface over time, leading to porosity and surface discoloration that undermine conductivity.

When to specify gold plating Selecting the right contact material for your tactile switch can make or break long-term reliability. Gold plating isn’t always necessary, but in the right applications, it’s indispensable. Low-level or signal circuits: When switching currents fall below 100 mA, even thin oxide films can prevent reliable conduction. Gold’s inert surface ensures clean, consistent contact resistance for microcontroller inputs, logic circuits, sensors, and communication interfaces. Mission-critical reliability: If system uptime or safety compliance is essential—such as in medical devices, aerospace, defense, or industrial safety systems—gold-plated switches prevent oxidation-related failures that could disrupt operations or endanger users. Harsh or uncontrolled environments: Designs exposed to moisture, sterilization cycles, or outdoor weathering benefit from gold’s corrosion resistance. Examples include surgical tools, outdoor telecom nodes, and HVAC or factory automation controls. Long lifecycle or high actuation counts: Gold plating resists fretting corrosion and wear, maintaining stable performance through hundreds of thousands to millions of actuations, critical in applications such as automotive HMI controls or consumer appliances with frequent use. Signal integrity and noise sensitivity: In instrumentation, medical sensing, and precision measurement, gold’s smooth, oxide-free surface minimizes contact noise and bounce, ensuring clean signal transitions and reducing the need for debouncing circuitry. Mixed-metal interfaces: Avoid combining gold with tin or silver on mating surfaces—galvanic reactions can accelerate corrosion. When other components use gold contacts, matching them with gold-plated tactile switches maintains uniform conductivity and compatibility. Choose gold-plated tactile switches when reliability, environmental resistance, or low-current signal integrity outweighs incremental cost. In these cases, gold is not a luxury; it’s engineering insurance.

Reliability in harsh and low-signal environments

Gold plating’s reliability benefits become evident under extreme environmental or electrical conditions.

Medical devices and sterilization environments

Surgical and diagnostic instruments often undergo repeated steam autoclaving or chemical sterilization cycles. Moisture and elevated temperatures accelerate corrosion in conventional materials. Gold’s nonreactive surface resists degradation, ensuring consistent actuation force and electrical performance across hundreds of sterilization cycles. This reliability directly impacts patient safety and device regulatory compliance.

Outdoor telecommunications and IoT

Field-mounted communication hardware—base stations, gateways, or outdoor routers—encounters moisture, pollution, and temperature fluctuations. In such applications, tin or silver plating can oxidize within months, leading to noisy signals or switch failure. Gold-plated tactile switches preserve contact integrity, maintaining low and stable resistance even after prolonged environmental exposure.

Industrial automation and control

Industrial environments expose components to dust, vibration, and cleaning solvents. Gold’s smooth, ductile surface resists micro-pitting and fretting corrosion, while its low coefficient of friction contributes to predictable mechanical wear. As a result, switches maintain consistent tactile feedback over millions of actuations, a vital factor in HMI panels in which operator confidence depends on feel and repeatability.

Aerospace, defense, and safety-critical systems

In avionics and safety systems, even transient failures are unacceptable. Gold’s resistance to oxidation and its stable performance across −40°C to 125°C enable designers to meet MIL-spec and IPC reliability standards. The material’s immunity to metal whisker formation, common in tin coatings, eliminates one of the most insidious causes of short-circuits in mission-critical electronics.

Mechanical contacts inherently produce bounce, a rapid, undesired make-or-break sequence that occurs as the metal contacts settle. Bounce introduces signal noise and may require software or hardware debouncing. Gold’s micro-smooth surface reduces surface asperities, shortening bounce duration and producing cleaner signal transitions. This improves response time and may simplify firmware filtering or eliminate RC snubber circuits.

Metal whisker mitigation

Tin and zinc surfaces can spontaneously grow metallic whiskers under stress, causing shorts or leakage currents. Gold plating’s crystalline structure is stable and does not support whisker growth, a key reliability advantage in fine-pitch or high-density electronics.

Thermal and mechanical stability

Gold has a low coefficient of thermal expansion mismatch with typical nickel underplates, minimizing stress during thermal cycling. It does not harden or crack under high temperatures, allowing switches to function consistently from cold-storage conditions (−55°C) to high-heat appliance environments (>125°C surface temperature).

Electrical characteristics: low-level signal switching

Many engineers underestimate how contact material impacts performance in low-current circuits. When switching below approximately 100 mA, oxide film resistance dominates contact behavior. Non-noble metals can form surface barriers that block electron tunneling, leading to contact resistance in the tens or hundreds of ohms. Gold’s stable surface keeps contact resistance in the 10- to 50-mΩ range throughout the product’s life.

Additionally, gold’s low and stable contact resistance minimizes contact noise, which can be especially important in digital logic and analog sensing circuits. For instance, in a patient monitoring device using microvolt-level signals, a transient resistance increase of just a few ohms can cause erroneous readings or false triggers. Gold plating ensures clean signal transmission even at the lowest currents.

Balancing cost and performance

It’s true that gold plating adds material and process costs. However, lifecycle analysis often reveals a compelling return on investment. In applications in which switch replacement or failure results in downtime, service calls, or warranty claims, the incremental cost of gold plating is negligible compared with the total system value.

Manufacturers help designers manage cost by offering hybrid switch portfolios. For example, C&K’s KMR, KSC, and KSR tactile switch families include both silver-plated and gold-plated versions. This allows designers to standardize on a footprint while selecting the appropriate contact material for each function: gold for logic-level or safety-critical inputs, silver for higher-current or less demanding tasks.

When specifying gold-plated tactile switches, engineers should evaluate both electrical and environmental parameters to ensure the plating delivers full value:

• Current rating and load type: Gold excels in “dry circuit” switching below 100 mA. For higher currents (>200 mA), arcing can erode gold surfaces; mixed or dual plating (gold plus silver) may be more appropriate.
• Environmental sealing: Use sealed switch constructions (IP67 or higher) when exposure to fluids or contaminants is expected. This complements gold plating and extends operating life.
• Plating thickness: For harsh environments or long lifecycles (>1 million actuations), specify a thicker gold layer (≥0.5 µm). Thinner flash layers (0.1 µm) are adequate for indoor or low-stress use.
• Base metal compatibility: Always ensure the plating stack includes a nickel diffusion barrier to prevent copper migration.
• Mating surface design: Gold-to-gold contacts perform best. Avoid mixing gold with tin on the mating side, which can cause galvanic corrosion.
• Actuation force and feel: Gold’s lubricity affects tactile response slightly; designers should verify that chosen switches maintain the desired haptic feel across temperature and wear cycles.

By integrating these considerations early in the design process, engineers can prevent many reliability issues that otherwise surface late in validation or field deployment.

Lifecycle testing and qualification standards

High-reliability applications frequently require validation under standards such as:

• IEC 60512 (electromechanical component testing)
• MIL-DTL-83731F (for aerospace-grade switches)
• AEC-Q200 (automotive passive component qualification)

Gold-plated tactile switches often exceed these standards, maintaining consistent contact resistance after 105 to 106 mechanical actuations, temperature cycling, humidity exposure, and vibration. Some miniature switch series, such as the C&K KSC2 and KSC4 families, can endure as many as 5 million actuations, highlighting how material selection plays a critical role in overall system durability.

Practical benefits: From design efficiency to end-user experience

For engineers, specifying gold-plated tactile switches yields several tangible advantages:

• Reduced maintenance: Longer life and fewer field failures minimize warranty and service costs.
• Simplified circuit design: Low and stable contact resistance can eliminate the need for additional filtering or conditioning circuits.
• Enhanced system reliability: Predictable behavior across temperature, humidity, and lifecycle improves compliance with functional-safety standards such as ISO 26262 or IEC 60601.
• Improved user experience: Consistent tactile feel and reliable operation translate to higher perceived quality and brand reputation.

For the end user, these benefits manifest as confidence—buttons that always respond, equipment that lasts, and interfaces that feel precise even after years of use.

Designing for a connected, reliable future

As electronic systems become smarter, smaller, and more interconnected, tolerance for failure continues to shrink. A single faulty switch can disable a medical device, interrupt a network node, or halt an industrial process. Choosing gold-plated tactile switches is therefore not simply a materials decision; it’s a reliability strategy.

Gold’s unique combination of chemical inertness, electrical stability, and mechanical durability ensures consistent performance across millions of cycles and the harshest conditions. For design engineers striving to deliver long-lived, premium-quality products, gold plating provides both a technical safeguard and a competitive edge.

In the end, reliability begins at the contact surface—and when that surface is gold, the connection is built to last.

Wi-Fi 7 enters 2026 with a crucial announcement made at the CES 2026 in Las Vegas, Nevada. The Wi-Fi Alliance is introducing the 20-MHz device category for Wi-Fi 7, aimed at addressing the needs of the broader Internet of Things (IoT) ecosystem. Add Wi-Fi 7’s multi-link IoT capability to this, and you have a more consistent, always‑connected experience for applications such as security cameras, video doorbells, alarm systems, medical devices, and HVAC systems.

The 802.11be standard, widely known as Wi-Fi 7, was drafted in 2024, and the formal standard followed in 2025. From Wi-Fi 1 to Wi-Fi 5, the focus was on increasing the connection’s data rate. But then the industry realized that a mere increase in speed wasn’t beneficial.

“The challenge shifted to managing traffic on the network as more devices were coming onto the network,” said Sivaram Trikutam, senior VP of wireless products at Infineon Technologies. “So, the focus in Wi-Fi 6 shifted toward increasing the efficiency of the network.”

The industry then took Wi-Fi 7 to the next level in terms of efficiency over the past two years, especially with the emergence of high-performance applications. The challenge shifted to how multiple devices on the network could share spectrum efficiently so they could all achieve a useful data rate.

The quest to support multiple devices, at the heart of Wi-Fi 7 design, eventually led to the Wi-Fi Alliance’s announcement that even a 20 MHz IoT device can now be certified as a Wi-Fi 7 device. The Wi-Fi 7 certification program, expanded to include 20-MHz IoT devices, could have a profound impact on this wireless technology’s future.

20-MHz IoT in Wi-Fi 7’s fold

Unlike notebooks and smartphones, 20-MHz devices don’t require a high data rate. IoT applications like door locks, thermostats, security cameras, and robotic vacuum cleaners need to be connected, but they don’t require gigabit data rates; they typically need 15 Mbps. What they demand is high-quality, reliable connectivity, as these devices sit at difficult locations from a wireless perspective.

At CES 2026, Infineon unveiled what it calls the industry’s first 20-MHz Wi-Fi 7 device for IoT applications. ACW741x, part of Infineon’s AIROC family of multi-protocol wireless chips, integrates a tri-radio encompassing Wi-Fi 7, Bluetooth LE 6.0 with channel sounding, and IEEE 802.15.4 Thread with Matter ecosystem support in a single device.

The ACW741x tri-radio chip also integrates wireless sensing capabilities, adding contextual awareness to IoT devices and facilitating home automation and personalization applications. Here, Wi-Fi Channel State Information (CSI) based on the 802.11bf standard enables enhanced Wi-Fi sensing with intelligence sharing between same-network devices. Next, channel sounding delivers accurate, secure, and low-power ranging with centimeter-level accuracy.

ACW741x is optimized for a 20-MHz design to support battery-operated applications such as security cameras, door locks, and thermostats that require ultra-low Wi-Fi-connected standby power. It bolsters link reliability with adaptive band switching to mitigate congestion and interference.

Adaptive band switching without disconnecting from the network opens the door to Wi-Fi 7 multi-link for IoT devices while maintaining concurrent links across 2.4 GHz, 5 GHz, and 6 GHz frequency bands. ACW741x supports Wi-Fi 7 multi-link for IoT, enhancing robustness in congested environments.

Multi-link for IoT devices

Wi-Fi operates in three bands—2.4 GHz, 5 GHz, and 6 GHz—and when a device connects to an access point, it must choose a band. Once connected, it cannot change it, even if that band gets congested. That will change in Wi-Fi 7, which connects virtually to all three bands with a single RF chain at no extra system cost.

Wi-Fi 7 operates in the best frequency band, enhancing robustness in congestion in home networks and interference across neighboring networks. “Multi-link for IoT allows establishing connections at all bands, and a device can dynamically select which band to use at a given point via active band switching without disconnecting from the networking,” said Trikutam. “And you can move from one band to another by disconnecting and reconnecting within 7 to 10 seconds.”

That’s crucial because the number of connected devices in a home is growing rapidly, from 10 to 15 devices after pandemic to more than 50 devices in 2025 in a U.S. and European home. Add this to the introduction of 20-MHz IoT devices in Wi-Fi 7’s fold, and you have a rosy picture for this wireless technology’s future.

According to the Wi-Fi Alliance, shipments of access points supporting the standard rose from 26.3 million in 2024 to a projected 66.5 million in 2025. And ABI Research projects that the transition to Wi-Fi 7 will accelerate further in 2026, with a forecast annual shipment number of Wi-Fi 7 access points at 117.9 million.

Awareness of LiDAR and advanced laser technologies has grown significantly in recent years. This is in no small part due to their use in autonomous vehicles such as those from Waymo, Nuro, and Cruise, plus those from traditional brands such as Volvo, Mercedes, and Toyota. It’s also making its way into consumer applications; for example, the iPhone Pro (12 and up) includes a LiDAR scanner for time-of-flight (ToF) distance calculations.

The potential of LiDAR technologies extends beyond cars, including applications such as range-finding in golf and hunting sights. However, the nature of the technology used to power all these systems means that solutions currently on the market tend to be bulkier and more power-intensive than is ideal. Even within automotive, the cost, power consumption, and size of LiDAR modules continue to limit adoption.

Tesla, for example, has chosen to leave out LiDAR completely and rely primarily on vision cameras. Waymo does use LiDAR, but has reduced the number of sensors in its sixth-generation vehicles: from five to four.

Overcoming the known power and size limitations in LiDAR design is critical to enabling scalable, cost-effective adoption across markets. Doing so also creates the potential to develop new application sectors, such as bicycle traffic or blind-spot alerts.

In this article, we’ll examine the core technical challenges facing laser drivers that have tended to restrict wider use. We’ll also explore a new class of laser driver that is both smaller and significantly more power efficient, helping to address these issues.

Powering ToF laser drivers

The main power demand within a LiDAR module comes from the combination of the laser diode and its associated driver that together generate pulsed emissions in the visible or near-infrared spectrum. Depending on the application, the LiDAR may need to measure distances up to several hundred meters, which can require optical power of 100-200 W. Since the efficiency of the laser diodes is typically 20-30%, the peak driving power delivered to the laser must be around 1 kW.

On the other hand, the pulse duration must be short to ensure accuracy and adequate resolution, particularly for objects at close distances. In addition, since the peak optical power is high, limiting the pulse duration is critical to ensure the total energy conforms to health guidelines for eye safety. Fulfilling all these requirements typically calls for pulses of 5 ns or less.

Operating the laser thus requires the driver to switch a high current at extremely high speed. Standing in the designer’s way, the inductance associated with circuit connections, board parasitics, and bondwires of IC packages is enough to prevent the current from changing instantaneously.

These small parasitic inductances are intrinsic to the circuit and cannot be eliminated. However, by introducing a parallel capacitance, it is possible to create a resonant circuit that takes advantage of this inductance to achieve a short pulse duration. If the overall parasitic inductance is about 1 nH and the pulse duration is to be a few nanoseconds, the capacitance can be only a few nano Farads or less. With such a low value of capacitance, the applied voltage must be on the order of 100 V to achieve the desired peak power in the laser. This must be provided by boosting the available supply voltage.

Discrete laser driver

Figure 1 shows the circuit diagram for a resonant laser-diode driver, including the resonant capacitor (Csupply) and effective circuit inductance (Lbond). A boost regulator provides the high voltage needed to operate the resonant circuit.

The circuit requires a boost voltage regulator, depicted as Boost voltage regulator (VR) in the diagram, to provide the high voltage needed at Csupply to deliver the required energy. The circuit as shown contains a discrete gate driver for the main switching transistor (FET), which must be controlled separately to generate the desired switching signals.

In addition, isolation resistance is needed between Cfilter and Csupply, shown in the diagram, to ensure the resonant circuit can operate properly. This is relatively inefficient, as no more than 50% of the energy is transferred from the filter side to Csupply.

Handheld equipment limitations

In smaller equipment types, such as handheld ranging devices and action cameras, the high voltage must be derived from a small battery of low nominal voltage—typically a 3-V CR2 or a 3.7-V (nominal voltage, up to 4.2 V) lithium battery—which is usually the main power source.

Figure 2 shows a comparable schematic for a laser-diode driver powered from a 3.7-V rechargeable lithium battery. Achieving the required voltage using a discrete boost VR and laser-diode driver is complex, and designers need to be very careful about efficiency.

Multiple step-up converters are often used, but efficiency drops rapidly. If two stages are used, each with an efficiency of 90%, the combined efficiency across the two stages is only 81%.

In addition, there are stringent constraints on enclosure size, and the devices are often sealed to prevent dust or water ingress. On the other hand, sealing also prevents cooling airflow, thereby making thermal management more difficult. In addition, high overall efficiency is essential to maximize battery life while ensuring the high optical power needed for long range and high accuracy.

Circuit layout and size

The high speeds and slew rates involved in making the LiDAR transmitter work call for proper consideration of circuit layout and component selection. A gallium nitride (GaN) transistor is typically preferred for its ability to support fast switching at high voltage compared to an ordinary silicon MOSFET. Careful attention to ground connections is also required to prevent voltage overshoots and ground bounce from disrupting proper transistor switching and potentially damaging the transistor.

Also, a compact module design is difficult to achieve due to efficiency limitations and thermal management challenges. The inefficiencies in the discrete circuit implementation mean operating at high power produces high losses and increased self-heating that can cause the operating temperature to rise. However, while short pulses can reduce the average thermal load, current slew rates must be extremely high. If this cannot be maintained consistently, extra losses, more heat, and degraded performance can result.

A heatsink is the preferred thermal management solution, although a large heatsink can be needed, leading to a larger overall module size and increased bill of materials cost. In addition, ensuring eye safety calls for a fast shutdown in the event of a circuit fault.

Bringing the boost stage, isolation, GaN FET driver, and control logic into a single compact IC (see Figure 3) achieves greater functional integration and offers a route to higher efficiency, smaller form factors, and enhanced safety through nanosecond-level fault response.

While leveraging resonant-capacitor charging to achieve short, tightly controlled pulse duration, this integration avoids the energy losses incurred in the capacitor-to-capacitor transfer circuitry. The fault sensing and reporting can be brought on-chip, alongside these timing and control features.

This approach is seen in LiDAR driver ICs like the Silanna FirePower family, which integrate all the functions needed for charging and firing edge-emitting laser (EEL) or vertical-cavity surface-emitting laser (VCSEL) resonant-mode laser diodes at sub-3-ns pulse width. Figure 4 shows how an experimental setup produced a 400-W pulse of 2.94 ns, operating with a capacitor voltage boosted to 120 V with a resonant capacitor value of 2.48 nF.

The driver maintains control of the resonant capacitor energy and eliminates any effects of input voltage fluctuations, while on-chip logic sets the output power and performs fault monitoring to ensure eye safety. The combined effects of advanced integration and accurate logic-based control can save 90% of charging power losses compared to a discrete implementation and realize an overall charging efficiency of 85%. The control logic and fault monitoring are configured through an I2C connection.

Of the two devices in this family, the SL2001 works with a supply voltage from 3 V to 24 V and provides a dual GaN/MOS drive that enables peak laser power greater than 1000 W with a pulse-repetition frequency up to several MHz. The second device, the SL2002, is a single-channel driver targeted for lower power applications and is optimized for low input voltage (3 V-6 V) operation. Working off a low supply voltage, this driver’s 80-V laser diode voltage and 1 MHz repetition rate are suited to handheld applications such as rangefinders and 3D mapping devices. Figure 5 shows how the SL2002 can simplify the driving circuit for a battery-operated ranging device powered from a 3.7 V lithium battery.

Shrinking LiDAR modules

LiDAR has been a key component in the success of automated driving, working in conjunction with other sensors, including radar, cameras, and ultrasonic detectors, to complete the vehicle’s perception system. However, LiDAR modules must become smaller and more energy-efficient to earn their place in future vehicle generations and fulfil opportunities beyond the automotive sphere.

Focusing innovation on the laser-driving circuitry unlocks the path to next-generation LiDAR that is smaller, faster, and more energy-efficient than before. New, single-chip drivers that deliver high optical output power with tightly controlled, nanosecond pulse width enable LiDAR to address tomorrow’s cars as well as handheld devices such as rangefinders.

STMicroelectronics held a virtual media briefing, hosted by Patrick Aidoune, General Manager, General Purpose MCU Division at ST, on November 17, 2025. The briefing was held before their flagship event, the STM32 Summit, where they launched STM32V8, a new generation of STM32 microcontrollers.

STMicroelectronics introduced its new generation microcontroller, STM32V8, under the STM32 class recently. Built on an innovative 18nm process technology with FD-SOI and phase change memory (PCM) technology included, this microcontroller is the first of its kind in the world.  It is the first under 20nm process to use FD-SOI along with an embedded PCM technology.

FD-SOI Technology

The FD-SOI is a silicon technology, co-developed by ST, which brought innovation in the aerospace and automotive applications. The 18nm process, co-developed with the Samsung Foundry, provides a cost-competitive leap in both performance as well as power consumption.

The FD-SOI technology gives a strong robustness to ionising particles and reliability in harsh operating environments, which makes it particularly suitable for intense radiation exposure found in earth orbit systems. The FD-SOI also helps reduce the static power consumption, along with allowing operations on a lower voltage supply, while sustaining harsh industrial environments as well.

Key Features

STM32V8’s Arm Cortex-M85 core, along with the 18nm process, gives it a clock speed of up to 800MHz, making it the most powerful STM32 ever shipped. It has also been embedded with up to 4 Mbytes of user memory in a competitive dual bank, allowing bank swapping for seamless code updates.

Keeping in mind the needs of developers, the STM32V8 provides for more compute headroom, along with more security and improved efficiency. Compared it is 40nm process node with the same technologies, the STM32V8 brings with it improved performance, higher density, and better power efficiency.

Industrial Applications

This new microcontroller is a multipurpose system to benefit several industries:

• Factory Automation and Robotics
• Audio Applications
• Smart Cities and Buildings
• Energy Management Systems
• Healthcare and Biosensing
• Transportation (ebikes)

Achievements

ST’s new microcontroller has been selected by SpaceX for its high-speed connectivity system in the Starlink Satellite System.

“The successful deployment of the Starlink mini laser system in space, which uses ST’s STM32V8 microcontroller, marks a significant milestone in advancing high-speed connectivity across the Starlink network. The STM32V8’s high computing performance and integration of large embedded memory and digital features were critical in meeting our demanding real-time processing requirements, while providing a higher level of reliability and robustness to the Low Earth Orbit environment, thanks to the 18nm FD-SOI technology. We look forward to integrating the STM32V8 into other products and leveraging its capabilities for next-generation advanced applications,” said Michael Nicolls, Vice President, Starlink Engineering at SpaceX.

STM32V8, like its predecessors, is expected to draw significant benefit from ST’s edge AI ecosystem, which is under continued expansion. Currently, the STM32V8 is in early-stage access for selected customers with key OEMs’ availability as of the first quarter 2026 and with broader availability to follow.

Apart from unveiling the new generation microcontroller, ST also announced the expansion of its STM32 AI Model Zoo, which is part of the comprehensive ST Edge AI Suite of tools. The STM32 AI Model Zoo has more than 140 models from 60 model families for vision, audio, and sensing AI applications at the edge, making it the largest MCU-optimised library of its kind.

This AI Model Zoo has been designed, keeping in mind the requirements of both data scientists and embedded systems engineers, a model that’s accurate enough to be useful and that also fits within their energy and memory constraints.

The STM32 AI Model Zoo is the richest in the industry, for it not only offers multiple models, but also scripts to easily retrain models, evaluate accuracy, and deploy on boards. ST has also introduced native support for PyTorch models. This complements their existing support for TensorFlow, Keras AI frameworks, LiteRT, and ONNX formats, giving developers additional flexibility in their development workflow. They are also introducing more than 30 new families of models, which can use the same deployment pipeline. Many of these models have already been quantised and pruned, meaning that they offer significant memory size and inference time optimisations while preserving accuracy.

Additionally, they also announced the release of STM32 Sidekick, their new AI agent on the ST Community, available 24/7. This new AI agent is trained on official STM32 documentation (datasheets, reference manuals, user manuals, application notes, wiki entries, and community knowledge base articles) to help users locate relevant technical data, obtain concise summaries of complex topics, and discover insights and documents. Alongside, they announced STM32WL3R, a version of their STM32WL3 tailored for remote control applications supporting the 315 MHz band. The STM32WL3R is a sub-GHz wireless microcontroller with an ultra-low-power radio.
