Differential Pair Routing for SI and EMI Control

Differential pairs have been used in PC boards for years to carry high-speed serial and high-speed parallel data, in a variety of bus formats. Many board designers and engineers believe the rules... [more]

An Intuitive Approach to Understanding Basic High-Speed Layout

What is a wire? At high speeds, it behaves very differently from what we were taught in college. This presentation on high-speed basics makes the subject intuitive in a way that’s easily understood.... [more]

A Practical Guide to RF and Microwave PCB Design

This is a session for embedded engineers and PCB designers who have never done RF board layout but are curious and want to have a go at it. It is not for experienced microwave engineers. This... [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]
