On the bottom left it is shown next to its accompanying vacuum tube power supply, not a single semiconductor used in the whole setup. Wiring is horrible, and its performance reflects that. But at least it looks nice. Uses a 2" diameter 902 CRT, and is based mostly on a 1945 RCA schematic for this tube. The CRT only runs at <600V (schematic specifies 577V, mine only runs on ~400V), which is remarkably low for a CRT but it definitely still hurts. Uses two 6SJ7 pentodes for vertical and horizontal amplification with a Type 884 thyratron for sawtooth generation. Has x-y mode and internal/line/external sync. Rectification is done with a Type 80 for B+ and a 6AU4 for the negative CRT supply (grounded anode). The tube could maybe use some magnetic shielding and I am trying to figure that out, but for now I just keep the power supply away from it to eliminate the interference. Whole thing uses a little over 60W when running and is fused accordingly. This is by far my highest-effort electronics project ever, and I am very glad to be done with it!

This circuit design for power supply on/off sequencing uses Schmidt triggers for triple-positive-rail timing purposes.

Recent design ideas have explored the utility of timed power supply ON/OFF sequencing and provided circuit designs to implement it.  Figure 1 shows a simple topology using Schmidt triggers for timing the turn ON and OFF of triple positive supply rails.  Here’s how it works.

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

Figure 1 This significantly simple supply sequencing scheme leverages Schmidt triggers.

Switching action begins with SPDT S1 in the OFF position which holds the C1 and C2 timing caps discharged.  The latter holds U1 pin 1 at 15v and therefore its pin 2 and the NFET Q2’s gate at zero, forcing the 5Vout rail OFF.

Meanwhile, C1’s discharged state holds U1’s pins 3 and 5 low so pins 4 and 6 sit high.  The former holds enhancement mode PFET Q1 and the 15Vout rail OFF, while the latter does the same for level shifter Q3, PFET Q4, and the 24Vout rail.

Therefore no power flows to the connected loads.  Yet, at least. Figure 2’s left side graphs the sequence of events initiated by actuating S1.

Figure 2 This plot shows power sequence timing when S1 is flipped ON and later flopped OFF.

C2 connects to ground through R3, quickly charging it to the Schmidt trigger low-going threshold in about R3C2 = 1mS.  This inverts U1 pin 2 to 15v, placing a net forward bias of 15 – 5 =10V on NFET Q2, turning it and the 5Vout rail ON.  Thus they will remain as long as S1 stays ON.

Meanwhile, reset of C1 has been released, allowing it to begin charging through R1 + R3.  The first thing that happens occurs at the end of T1 when U1 pin 3 reaches the ~9V Schmidt threshold.  Since the timeout duration is proportional to C1, any desired interval can be chosen with an appropriate RC product.  U1 pin 4 then snaps low, PFET Q1 turns ON and 15Vout goes active.

Of course C1 continues to charge, so at T2 U1 pin 5 also reaches its triggering threshold.  Then its pin 6 snaps low, turning ON Q3, Q4 and 24Vout.  The ratio R4 = 10 R5/(15 – 0.7) was chosen to apply an adequate and safe ~10V drive to Q4’s gate, independently of 24Vin. The S1 flip ON sequence is now complete.

The right side of Figure 2 shows what happens when S1 subsequently flops OFF. First, C1 is promptly discharged through R3, turning OFF Q1, Q3, Q4 and thereby 15Vout and 24Vout, putting them and whatever they power to sleep.  Meanwhile C2 begins ramping up, taking T3 to get to U1’s threshold.  When it completes the trip, pin 2 goes low, turning Q2 and 5Vout OFF. 

Turnoff sequencing is therefore complete.  Nighty night.

Details of the design include D1 and D2.  Their purpose is to make the sequencer’s response to losing and regaining of the input rail voltage orderly, and to do it regardless of whether S1 is ON or OFF.  If  S1 is OFF, then all output rails remain low and (a safe) nothing occurs when the supply voltages return.  If it’s ON, then a normally timed (and therefore safe) power-up sequence is executed.

Note that the MOSFETs should be chosen for adequate voltage and current handling capacities.  Because Q1 has 15v of gate drive and Q2 and Q4 get 10v, none need be sensitive logic-level types.

Okay.  But what if you also need to sequence a negative supply rail?  Figure 3 shows how.

Figure 3 This power switching circuit works with a negative rail.

When the U1 inverter’s input rises above the Schmidt trigger voltage, its output snaps low, causing the 2N3906  to pass Ic = (+15Vin – 0.6)/15k = 0.96mA.  This develops a 10.6V that’s independent of –Vin across the 11k resistor, saturating the NFET.  If symmetrical polarity rails (e.g. +/-15v) are needed, Figure 3 can be added to Figure 1 to provide the negative side with no other modifications required.

Stephen Woodward‘s relationship with EDN’s DI column goes back quite a long way. Over 200 submissions have been accepted since his first contribution back in 1974.  They have included best Design Idea of the year in 1974 and 2001.

Rohde & Schwarz successfully certifies the testing of its hybrid eCall and the Next Generation eCall test solution done by Cetecom Advanced, a leading independent test laboratory for product testing and worldwide certification for devices from various branches like communication technologies, automotive, medical technology, payment & identification. The Rohde & Schwarz solution is based on the CMX500 radio communication tester with the latest eCall option to ensure compliance with the latest eCall regulations and standards.

The hybrid eCall test specification EN 18052 states that a hybrid system must combine different transmission paths and protocols to make sure an eCall reliably reaches its destination. In practice, this means a vehicle uses NG eCall functions (IP/IMS-based voice and data over 4G/5G) but can automatically fall back to available classic CS eCall (2G/3G) transport paths when coverage or service quality degrades. Manufacturers need to validate hybrid implementations to ensure they can trigger calls, transmit the minimum set of data (MSD), maintain GNSS positioning, and deliver intelligible voice quality across multiple network scenarios, including voice over New Radio (VoNR), voice over LTE (VoLTE), and circuit-switched fallback. Tests must demonstrate that a system remains robust during handovers and under degraded radio conditions, while also complying with relevant CEN, ETSI, 3GPP, and national requirements.

“We use the solution for functional tests and protocol conformity tests as well as for the type-approval of In-Vehicle Systems (IVS) that implement hybrid eCall and NG eCall,” says Thomas Reschka, Senior Technical Consultant at cetecom advanced.

Rohde & Schwarz has updated its eCall evaluation solution, CMX-KA09x, to support compliance with EN 18052:2025 and EN 17240:2024+A1:2026. The CMX-KA099 option completed Public Safety Answering Point (PSAP) test scenarios in accordance with EN 18052:2025, while the CMX-KA098 option completed PSAP test scenarios in accordance with EN 17240:2024+A1:2026. This marks an important step toward meeting European requirements for NG eCall test systems. The test environment allows the simulation of the real world mobile network conditions and the emulation of various network scenarios. This is a significant advantage in preparing for certifications or the market launch of new vehicle models.

Strengthening Microchip Technology’s data center solutions portfolio, the retimers support high-bandwidth architectures while helping reduce integration complexity

As AI workloads continue to scale, the data center architects show limitations by signal reach and rising latency, leaving valuable memory resources underutilized across large GPU clusters. These challenges boost as interconnect speeds increase. At 64 GT/s (giga transfers per second), signal integrity limitations can restrict system scale and burden server architectures. In response, Microchip Technology releases XpressConnect PCIe 6.0 and CXL 3.1 retimers to enable memory expansion and resource disaggregation in large-scale AI fabrics.

The retimers extend signal reach beyond conventional PCIe Gen 5 and Gen 6 electrical limits, enabling more flexible system designs across complex baseboards, riser cards, and cabled interconnects. The retimers are engineered to help address these challenges by enabling higher-bandwidth connectivity while supporting the stringent thermal requirements of modern AI fabrics that require power budgets. XpressConnect retimers achieve a pin-to-pin latency of less than 12 ns, approximately 80% lower than PCIe 6.0 specifications. This low-latency performance helps improve utilization of AI accelerators and GPUs by reducing data stalls in high-density AI clusters.

“AI data centers are increasingly constrained not by compute, but by the ability to move data efficiently across the system. As PCIe 6.0 pushes speeds to 64 GT/s, signal reach and latency become critical design challenges,” said Brian McCarson, corporate vice president and GM of Microchip’s data center solutions business unit.

Our XpressConnect retimers are designed to act as the high‑performance nerve center of the AI server, helping customers build more scalable, power‑efficient fabrics by reducing latency and improving connectivity across dense GPU clusters. This system‑level approach allows data center architects to reclaim underutilized resources and improve overall platform efficiency at scale.

The XpressConnect retimers round out Microchip’s data center portfolio and are engineered to work alongside the company’s 3-nm Switchtec PCIe Gen 6 switches, Adaptec SmartRAID controllers and Host Bus Adapters (HBAs), and Flashtec NVMe controllers, helping enable a pre-validated, interoperable fabric. Microchip’s XpressConnect PCIe Gen 6 and CXL 3.1 retimers can integrate with PCIe Gen 3, Gen 4, and Gen 5 platforms as required, helping reduce time to market. The retimers also connect into Microchip’s ChipLink diagnostic ecosystem, delivering a unified graphical user interface for real-time 2D eye capture and four-level pulse amplitude modulation (PAM4) telemetry. These capabilities help data center operators monitor link health more effectively and simplify troubleshooting, which can help reduce the total cost of ownership.

Engineered as an industry-standard, drop-in solution, XpressConnect retimers are designed to help reduce the risk of single-vendor dependency for hyperscalers. Additionally, the devices support flexible link bifurcation configurations (1×16, 2×8, and 4×4) and align with widely adopted retimer footprint guidelines, while providing enterprise-class features such as hot-plug support and end-to-end data integrity.
