Decade-long partnership overcame complex payload design challenges to empower next-generation environmental research from space

• A deeply-coupled partnership between TI and SAC-ISRO helped enable the mission payloads for the NISAR satellite, which is currently orbiting Earth.
• TI’s space-grade power management, mixed signal and analog technologies optimize system performance and allow the satellite to operate in the harsh environment of space over the mission’s lifetime.
• NISAR is the first satellite to use dual-band synthetic aperture radar technology to monitor the Earth’s ecosystems, natural hazards and climate patterns.

Texas Instruments (TI) semiconductors are enabling the radar imaging and scientific exploration payloads for the NASA-Indian Space Research Organization (ISRO) synthetic aperture radar (NISAR) satellite, which was recently launched into orbit. The launch of the satellite culminates a decade-long partnership between TI and the ISRO to optimize the performance of the electronic systems responsible for this Earth-observation mission. NISAR is equipped with TI’s radiation-hardened and radiation-tolerant products that enable designers to maximize power density, precision and performance in their satellite systems.

Engineering a first-of-its-kind satellite for Earth observation

The ISRO describes NISAR as the first Earth-observation mission to use dual-band synthetic aperture radar (SAR) technology, enabling the system to capture precise, high-resolution images during the day, night and all weather conditions. TI’s technology is enabling the satellite’s next-generation capabilities through efficient power management, high-speed data transfer, and precise signal sampling and timing.

The NISAR satellite will image the entire planet every 12 days, offering scientists greater understanding of changes to Earth’s ecosystems, ice mass, vegetation biomass, sea-level rise and groundwater levels. The agencies also expect the data to improve real-time monitoring of natural hazards such as earthquakes, tsunamis, volcanoes and landslides.

“From selecting the right products to ensuring consistent support across development cycles, TI’s technical expertise helped us navigate complex payload requirements,” said Shri Nilesh Desai, Director, Space Applications Centre (SAC), ISRO. “A deeply coupled partnership, specifically focused on high-impact mixed signal and analog semiconductors, enabled ISRO to meet the system-level requirements for a satellite in low Earth orbit. Together, we achieved the space-grade performance standards needed for this important mission.”

We are told that LED-based lighting will provide a very long service life per bulb, but here comes “Sportin’ Life” again (from Porgy and Bess) to put the lie to that claim. (It ain’t necessarily so.)

These four LED lamps each went dark after only a few months of service despite their packages’ promise (Figure 1).

Figure 1 Four LED bulbs that failed after a few months despite their service life being over 20 years.

Similarly, one of the five LED lamps in this ceiling fixture also went dark after only a few months of service (Figure 2).

Figure 2 One in five LED bulbs in this ceiling lamp was rendered nonfunctional only after a few months.

In my eighty years in this world, I have only twice seen a new incandescent lamp fail so soon after being put into service. One lamp had a service life of thirty minutes and the other one died almost instantly.

I tried to cut open one of the four failed conical LED lamps to see what specifically had gone wrong, but I couldn’t manage to penetrate the shroud. Those plastic bulb enclosures were made of really tough stuff. Failing in that effort, I simply threw the four of them out.

Nevertheless, four for four strikes me as a pretty shabby history. I replaced each of the four with products from a different manufacturer, and so far, since pre-pandemic times, those LED bulbs are still working.

It can be done.

Design Idea (DI) contributors have recently explored various possibilities for ON/OFF power control using just a momentary contact “shiny modern push-button,” many of which build off of Nick Cornford’s “To press on or hold off? This does both.”

These ideas are interesting, and they’ve suggested a different notion. Figure 1 takes the one-button power control concept a bit further. It uses its button to provide six bits of resolution to a kilowatt of variable AC power, addressing adjustable applications like heating blankets, lamp dimming, motor speed, etc. I like it because, well, shouldn’t there be a bit (or even six) more to life than just ON/OFF?

Figure 1 Variable AC power control with a simple pushbutton. When S1 is pushed, counter U1 ramps through the 64 DAC codes in a 210 / 120Hz = 8.5-second cycle and stops on any selected power setting when S1 is released.

Wow the engineering world with your unique design: Design Ideas Submission Guide

Power control method

The power control method employed in Figure 1 is variable AC phase angle conduction via thyristor Q3. It’s wired in the traditional way except that the 6-bit DAC driven by CMOS counter U1 fills in for the usual phase adjustment pot. Because, unlike Q3, the DAC circuitry isn’t bidirectional, the D1-4 rectifier is needed to feed it DC and keep it working and counting through 60-Hz alternations.

Full power Q3 efficiency is around 99%, but its maximum junction temperature rating is only 110 °C. Adequate heatsinking of Q2 will therefore be necessary if output loads greater than 200 W are expected.

Adjusting U1 to the desired power setting is accomplished by pushing and holding switch S1. This connects the 120-Hz full-wave rectifier signal from the D1-D4 bridge to the Schmitt trigger formed by R2, R3, and U1’s internal non-inverting q0 input buffer.

The subsequent division of the 120 Hz signal by U1’s ripple divider chain makes flip-flop q5 toggle at 120/25 = 3.75 Hz, q6 at 120/26 = 1.875 Hz, and so forth down to q10 at 120/210 = 0.117 Hz. This gives a ramp time of 8.5 seconds for the full 0 (= full OFF) to 63 (= full ON) code cycle. Meanwhile, digital integration of the raw signal from switch S1 by U1’s counters suppresses switch contact bounce.

When the desired power setting (lamp brightness, motor speed, etc.) is reached, release the button, i.e., just let go! However, due to the fairly rapid toggle rate of the lower counter stages, a bit of practice may be required to accurately hit a target setting on the first try.

DAC topology

The DAC topology is straightforward. Just six (R4 through R9) binary-weighted resistors make up a summing network that produces a 0-V to 15-V input to the Q1 Q2 complementary current-mode output buffer.

Q1 provides nominal compensation for Q2’s Vbe offset and tempco, as well as sufficient current gain to allow use of multi-megohm resistances in the summation network. This is important because operating power for the DAC is basically stolen from Q3’s phase control signal.

This (as you probably noticed), nicely avoids the need for a separate power supply, but it provides only microamps of current for U1 and friends. So, a power-thrifty topology was definitely needed.

DAC reference Z1 is remarkably content with its meager share of this starvation diet. It maintains a usefully constant regulation despite only a single-digit microamp bias, which is impressive for an 11-cent (in singles) part. Meanwhile, U1 daintily sips only tens of nanoamps.

R11 and C3 provide an initial reset to OFF when power is first applied.

At this point, you might reasonably ask: Is this scheme any better than a simple pot with a twistable knob? Well, don’t forget the “shiny modern push-button” factor.

Stephen Woodward’s relationship with EDN’s DI column goes back quite a long way. Over 100 submissions have been accepted since his first contribution back in 1974.

Smartphones have become some of the most ubiquitous devices in modern history. For most of us, the smartphone is an indispensable tool to not only communicate, but to manage our lives – work, personal relationships, travel, shopping, entertainment, photography, video creation. In short, smartphones have become a hub for life. 

 The touchscreen was transformational in the smartphone’s adoption and use. But in the future, the smartphone is set to become a platform for immersive experiences. And when aligned to innovations that will extend battery life and even see smartphones harvesting their own energy, along with new ways to stay constantly connected, their usefulness will only increase.  

 A powerful processor in your pocket

Smartphones have become incredibly powerful processing devices. Indeed, in comparison to the most powerful supercomputers of the 1980s, today’s smartphones can process information more than 5,000 times faster. 

In some ways, however, the way that we interact with our smartphones has progressed least since their arrival. For many people, the touchscreen remains the primary – if not only – way that they access and view the interactive services and rich experiences provided by their smartphone. The coming years will see that transformed and, with it, the idea of what a smartphone is. 

A reduced reliance on the smartphone display as the principal way to interact with the device and receive information fundamentally changes the role of the smartphone. As a powerful computing device in its own right, but also connected to cloud-based computing resources, the smartphone potentially becomes a platform for delivering immersive experiences and valuable services to the user in numerous new ways.  

New models for smartphone interaction

Voice assistants have become one of the first steps into a new world of accessing services via our smartphones. Whether issuing voice commands and queries directly into the device or having these relayed via connected headphones and earbuds, consumers are realising the convenience of voice and audio interaction. An additional benefit, of course, is that the smartphone itself can remain in a pocket or bag, out of harm’s way. 

Eyeglasses featuring augmented reality (AR) display technology are an ideal solution. These can visually display directions in the user’s eyeline, while also overlaying other useful or interesting information. With more information and experiences layered over the real world, discovering a new city will be more rewarding than ever before, with less potential for a misstep along the way. 

Artificial intelligence (AI) will also enable proactive and predictive services that help us manage our daily lives. For example, by understanding the current traffic conditions, AI might bring an alert for your next meeting across town 30 minutes earlier. With the alert appearing on your smartwatch, more efficient travel could be proposed, with directions to the closest public transport appearing in your eyeglasses’ AR display. 

Gesture recognition and haptic feedback

Gesture recognition is emerging as another way to interact with services provided by smartphones. Less obvious that either using a touchscreen or voice, subtle gestures to make or answer calls or respond to messages will be quick and convenient methods of interaction. Who knows, you might well respond to the latest message received with an actual thumbs up, rather than having to find and type the emoji itself.  

We might be on the cusp of a whole new vocabulary of gestures as commands. Google is one company looking at how devices can be controlled by natural human gestures, many of which we use subconsciously. Other advances in hardware, such as the latest generation of Time-of-Flight (ToF) sensors, will support more accurate detection of gestures in and around smartphones. 

Haptic feedback is the use of vibrations or sensations to enrich the experience of using a device. At a basic level, most of us already experience haptic feedback in our smartphone use. Vibrations rather than a ringtone to signify an incoming call is a simple example, but the nature and application of haptic feedback is rapidly evolving. 

Imagine shopping online and being able to ‘feel’ different types of fabric through haptic feedback via your smartphone’s screen. Subtle vibrations from different parts of smart eyeglasses could be used to enrich visual experiences or help with directions. Research is even looking at ultrasound and “mid-air” haptics, where the sensation of physical touch is created in the air. Such haptic feedback could augment gesture control or enhance touchless interfaces. 

The potential for neural interfaces

Though still in its early stages, the idea of interacting with devices merely by thinking is becoming more real. Various non-invasive neural interfaces are in development.  

Electroencephalography (EEG) sensors placed on the head via headsets, or potentially even embedded in hats and headbands, are a direct way to tap into the brain’s activity. Neural wristbands detect signals from nerves connecting the brain to an individual’s hands, whereby just thinking about a gesture or action could act as a command.  

So-called “silent speech” interfaces detect subtle changes in expression or movements in vocal chords, where simply mouthing words would be detected as accurately as voice. Data from wearables such as smartwatches, rings, and earbuds, could identify cognitive load and emotional state, triggering proactive alerts, suggestions, or experiences to help alleviate issues.  

Projecting further into the future, neural interfaces and advanced haptic feedback could be combined to create a new world of deeply immersive experiences, all powered by the not-so-humble smartphone. 

Always connected

Of course, this vision of the smartphone as a platform for new services and experiences relies on an almost constant connection to cloud-based computing resources. Fortunately, alongside the innovations in smartphone interface technologies, we’re seeing continued development of technologies that ensure we remain connected, wherever we are. 

As we recently highlighted, the need to connect the world of increasingly intelligent “things” – not only smartphones, but billions of sensors, machines, and consumer products – is being supported by innovation in communications technology. This includes further evolution of established infrastructure, with 6G telecommunications networks arriving in the coming years, but also the significant expansion of satellite-based communications networks.  

When the smartphone arrived it was exactly that: a phone with additional capabilities. We can all appreciate how far it has moved beyond that simple description, and over a relatively short period of time. While we might need a new name for the device, we certainly need to change our understanding of what this powerful pocket processing device represents.

New ways to interact with our smartphones, innovation in the delivery of seamless immersive experiences, universal connection, and improved battery life and self-charging, will see them become the primary digital platform for every aspect of our lives.

Arc generator modules may be small in scale, but they offer big opportunities for hands-on exploration in electronics. Whether you are experimenting with arc simulation, testing circuit behavior under fault conditions, or simply curious about high-voltage phenomena, these minuscule modules provide a safe and accessible way to dive into the fundamentals.

This blog will present hands-on tips and tricks for working with hobby-grade arc generator modules and circuits—ideal for curious minds and budding engineers eager to explore high-voltage experimentation.

There are several methods for generating electric arcs. However, this post will focus on how to achieve extra-high voltage levels using simple electronic circuits. The spotlight is on a widely available, budget-friendly arc generator module kit designed for DIY enthusiasts. It’s an accessible way to dive into high-voltage experimentation without breaking the bank.

Take a look at the kit below, along with its key technical specs to help you understand what it offers.

• Input voltage: 3.7 V to 4.2 V DC
• Input current: < 2 A
• Output voltage: ~15 kV
• Output current: ≤ 0.4 A
• Ignition distance (high voltage bipolar): ≤ 0.5 cm

Figure 1 This compact arc generator kit delivers around 15-kV output using only a handful of components. Source: Author

This is arguably one of the elementary and most accessible kits for electronics enthusiasts looking to explore high-voltage applications. The module requires minimal setup skills, with no circuit-level adjustments needed. While the power output is not exceptionally high, even a minor mishap can result in serious electrical burns. That said, with proper safety precautions in place, the system can produce stunningly high-frequency arcs.

Now, let’s take a look at the schematic diagram to understand how the circuit works.

Figure 2 The schematic diagram demonstrates how the kit produces high voltage through a minimal circuit design. Source: Author

Examining its internal electronics reveals a single-transistor oscillator at the heart of the circuit. This simple yet effective configuration allows high-voltage generation from standard battery cells.

Functionally, it acts as a step-up (booster) transformer system, where a feedback loop controls the switching of a power transistor. The secret to high-voltage output lies in the transformer’s winding setup. It uses two primary coils—main and feedback—alongside a secondary winding that can produce voltages soaring into the kilovolt range.

The diode’s most critical function in this oscillator circuit is to block the reverse voltage pulse generated by the transformer’s collapsing magnetic field. This action is essential for two reasons; it prevents damage to the transistor and ensures a clean transition to the “off” state.

Next is another compact high-voltage boost module (sometimes labelled as XKT203-33) capable of generating up to 30 kV. Specifically engineered for pest control applications, it finds use in devices aimed at eliminating mosquitoes, cockroaches, and other small insects. Despite its impressive output, the module operates efficiently with minimal power input, making it ideal for battery-powered or low-power systems.

The image below presents the aforesaid module alongside its internal schematic for reference. A closer look at the available schematic highlights the use of proprietary components, with a Delon voltage doubler circuit strategically placed at the output stage to deliver the required 30 kV.

Figure 3 The 30-kV module achieves high-voltage generation through an elegantly minimal design. Source: Author

Interestingly, a closer look at two seemingly popular kV generator modules shows that even humble jellybean components can handle the task. Still, integrating custom parts might elevate performance and efficiency.

But before jumping to conclusions, consider this alternative design idea for building your own kV generator module, an approach many have explored with intriguing results. Let’s take a quick look.

Figure 4 The blueprint shows how to generate high-voltage output using an automotive ignition coil. Source: Author

This approach simply utilizes a universal automotive ignition coil to produce high-voltage output, as depicted in the self-explanatory diagram above.

At its core, an ignition coil consists of three main components: a primary winding, a secondary winding, and a laminated iron core. Secondary winding contains significantly more turns of wire than the primary, creating a turn ratio that directly influences the voltage increase. There is a fairly typical range for the ignition coil turns ratio, usually between possibly 50:1 to 200:1, with 100:1 probably being the most common.

Just to add, in an inductive ignition system, the primary winding is typically energized with 12 V or 24 V. When this current is suddenly interrupted, a high-voltage EMF is induced in the secondary winding—often reaching 20 kV to 40 kV—more than enough to jump across a spark gap.

To break it down further, a single switching action by a transistor (BJT/IGBT/MOSFET) initiates the ignition process by allowing current to flow through the ignition coil’s primary winding. The current charges the primary coil, storing energy in its magnetic field. When the transistor turns off and interrupts the current, the magnetic field begins to collapse.

In response, the coil resists the sudden change, causing a rapid rise in voltage across the secondary winding, ultimately generating the high-voltage spark needed for ignition. It’s enough to ionize the air to create a spark.

Back to the subject matter, when driving the ignition coil through either an IGBT or a MOSFET, try experimenting with appropriate square wave pulses. Start with low frequencies around 150 to 350 Hz and duty cycles between 25% and 45% (just to get a feel for the response).

Heads up! Touching the high voltage from the ignition coil will definitely sting. It won’t kill you, but it will make you regret it.

That wraps up this post. I have got plenty more practical tips and insights lined up, so expect fresh content soon. This is just one piece of a much larger puzzle.
