Designing the Signal Return Path

When designing a PCB, the signal routing and its return are critical to the circuit working properly. Great care is usually given to routing the signals, but often the return portion is the last... [more]

Mechanical Design to Control EMI

As most engineers and designers are aware, EMI occurs because some mechanical structure, within or attached to our system, is capable of resonating and radiating electromagnetic field energy. Those... [more]

How to Fight Magnetic Noise Gremlins

Have you ever had a noise-sensitive circuit and tried to find the noise source? Even after you completely encased sensitive portions in all sorts of shielding, you still had noise? It’s very... [more]

The Butterfly Effect in PCB Design: Optimization of High-speed Lines for an FMC Carrier Board

When signals start to get affected by the physical characteristics of the PCB, things start to get a little tricky. A simple point-to-point connection won’t be enough to keep the integrity of the... [more]
