The Case for Split Ground Planes

Some experts say you should never use a split ground plane. Others say you should use a split ground plane to control noise. When is the right time to split a ground plane? We will explore the... [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]

Novel Power Distribution System Design

This presentation will present a simple EM physics and geometry-based approach to designing power distribution networks on PCBs. From input power connection to the IC die, the simple rules discussed... [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]
