IoT PC Board Design and Layout

Circuit boards for the IoT world (Internet of Things) are often driven by the need for low power dissipation, low cost (which drives very low layer count), moderate to high-density and mixed-signal... [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]

Does a Differential Pair Need a Return Plane?

A differential pair is any two transmission lines. When each transmission line has a return plane, its pretty clear how the differential impedance is related to the geometry. But what if there is no... [more]

Effective PCB Design: Techniques to Improve Performance

Tired of failing EMC certification over and over? Join the crowd. Shrinking IC geometries and a resulting increase in switching speeds make designing compliant printed circuit boards more... [more]
