The rollout of 5G technology has brought unprecedented speed, ultra-low latency, and massive device connectivity. At the heart of this revolution lies a critical hardware component: the millimeter-wave (mmWave) Printed Circuit Board (PCB). Unlike traditional PCBs used in consumer electronics, mmWave PCBs operate at extremely high frequencies (typically 24 GHz to 39 GHz and beyon...

tl;dr: i'm making an expansion board for the rpi pico that controls 12v 4-pin pc fans via pwm using txu0204 chips to translate between 3v3 and 5v; do the circuit and pcb designs look acceptable?

i'm working on an expansion board for the raspberry pi pico. the purpose of this board is to control fans via pwm and re...

Hello everyone, currently I have a big issue related to glitch detection in Innovus and PrimeTime
In PrimeTime it was detected a lots of glitch violation up to thousands !!! While in Innovus it see nothing so it can not fix in Innovus. Both tool use CCSN noise model
1. I have checked the threshold both tool in Innovus it set hard threshold while in PT it was change(I...

Hi everyone,

I’m trying to understand how to choose a suitable capacitor for smoothing the output of a DC power supply.

I understand that a capacitor helps reduce voltage ripple, but I’m not sure how to estimate the required capacitance in a practical circuit.

How do load current, supply frequency and the acceptable ripple voltage affect th...
