Switch enables high-speed digital loopback testing

Menlo Micro’s MM5620 dual DP3T switch operates from DC to 20 GHz, delivering up to 64 Gbps (64 GT/s) while maintaining high data signal integrity. This fully integrated system-in-package (SiP) permits differential loopback testing in high-speed…

The profile of a data-driven IC design verification tool

Each generation of IC design technology introduces new levels of complexity, and logic verification teams face a host of new challenges due to this dramatic rise in IC design complexity. As a result, design closure, knowing engineers have done…

Universal purpose optoelectronic logic elements

The possibility of creating passive and active optoelectronic logic elements simultaneously performing the functions AND, NAND, OR, NOR, XOR, XNOR is considered. Passive logic elements, unlike active ones, do not have their own power sources…

Streaming music reception: implementation differentiation

In the more than a quarter century that I’ve been using and writing about tech devices for EDN (whether because I owned them or just temporarily got my hands on a review unit), a few stand out…in a good way, mind you, versus any of the innumerable…

A look at conical inductors

There comes a time in RF and microwave work when one must introduce DC power into a signal carrying line without degrading the high frequency action of that line. A commonly used device is called a “bias-tee”. The following sketch illustrates…

How PMICs operate in image sensor-based designs

Modern electronic devices often have at least a few analog rails in their power profile. This is especially applicable in consumer electronics, automotive, medicine, and smart home devices. Building an optimized power profile requires devices…

D-band power amplifier ratchets up the power

NEC has developed a GaAs-based power amplifier that achieves what it believes is the world’s highest output power of 10 mW in the 150-GHz band. Built with mass-producible GaAs technology, the device targets mobile access and fronthaul/backhaul…
