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]

The PCB Design Process from Cradle to Grave

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]

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]

Power Delivery System Design

With the advent of ICs with multiple power rails at very high currents, the design of the power delivery system in a modern product is often more difficult than routing the PCB to ensure good signal... [more]
