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]

This half-day course is an overview (past, present, and future) of the interactions of processes, people and technologies involved in the complete lifecycle of a PCB design. This course is designed... [more]

From DC to AC - Power Integrity and Decoupling Primer for PCB Designers

Supply voltages decrease with every new silicon generation, contributing as well to the goal of reducing power consumption of our electronics. Coupled with the resulting shrinking noise margins for... [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]
