Routing Digital Boards to Avoid Problems

There are many ways to route a PCB, some much more effective for signals than others. The first design rule is that the board must work properly, so it is important to have a plan that addresses... [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]

PC Board Grounding to Control Noise, EMI and Signal Integrity

When time-varying (AC) signals travel in the transmission lines of a board, state-changing electric and magnetic fields are present. These fields, when not controlled, are the source of noise and... [more]

The Mystery of Bypass Capacitors

How do you design a high-speed digital circuit with enough bypass caps in the right area to supply all the peak power demands? You can’t listen to all the expert advice because it seems they can’t... [more]
