No floating nodes
The schematic below was screen-shot from a LinkedIn group. I heard alarm bells go off in my head when I saw it (Figure 1).
Figure 1 A suggested application note diagram found in a LinkedIn group with a floating node between C4 and C5 that could…
The promise of OTS-only memories for next-gen compute
For several decades, the semiconductor industry has been looking for alternative memory technologies to fill the gap between dynamic random-access memory (DRAM), the compute system’s main memory, and NAND flash—the system’s storage medium—in…
Efficient voltage doubler is made from generic CMOS inverters
When a design needs auxiliary voltage rails and the associated current loads are modest, capacitor pump voltage multipliers are often the simplest, cheapest, and most efficient way to make them.
Wow the engineering world with your unique design:…
Parsing PWM (DAC) performance: Part 3—PWM Analog Filters
Editor’s Note: This is a four-part series of DIs proposing improvements in the performance of a “traditional” PWM—one whose output is a duty cycle-variable rectangular pulse which requires filtering by a low-pass analog filter to produce…
Transceivers enable contactless USB2 connectivity
Two 60-GHz V-band transceivers, the ST60A3H0 and ST60A3H1 from ST, offer short-range cable-free connectivity at up to 480 Mbps. Operating in half-duplex mode, these compact devices enable embedded USB2 (eUSB2), I2C, SPI, UART, and GPIO RF tunneling.
The…
Wireless modules expand development options
Quectel has launched four new Wi-Fi and Bluetooth modules to provide designers with a greater array of options in terms of size, cost, and power efficiency. Joining the company’s portfolio of IoT modules are the FCU741R Wi-Fi 4 module and…
Current sensor helps shrink EV onboard chargers
Asahi Kasei’s CZ39 series of coreless current sensors allows OEMs to design smaller and lighter onboard chargers for electric vehicles. With its fast response time, low heat generation, and noise immunity, the CZ39 enables current measurements…
Switchers tout single-stage multi-output operation
InnoMux-2 is a family of GaN-based flyback switcher ICs from Power Integrations that offers multiple independently regulated outputs. The switchers consolidate AC/DC and downstream DC/DC conversion stages into a single chip, providing up to…
Integrated motor drivers save PCB space
Along with a dsPIC33 digital signal controller (DSC), motor drivers from Microchip pack a three-phase MOSFET gate driver and optional LIN or CAN FD transceiver. These integrated devices reduce the component count, PCB size, and complexity of…

APEC 2024, Day 2: Daily Briefing Video
During Day 2 of APEC 2024, Power Electronics News editor-in-chief Maurizio Di Paolo Emilio and EDN editor-in-chief Majeed Ahmad underscored the significance of silicon and silicon carbide technologies alongside passive components, gallium…
Photosensitivity: Seizures from displays
A couple of years ago, I described having witnessed someone undergo an epileptic seizure at the company where I was employed at the time. I tried to keep cool and collected while writing about that incident, but the truth be told, it was jarring.…
