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]

Feeding the Beast: Consumption-Based PCB Design

A step-by-step guideline for determining the PCB design requirements based on device energy consumption requirements. Wave cycle times and transmission line capacity form the basis of 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]

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]
