Via and Trace Currents and Temperatures

Stop thinking about current density! In this 30-minute video, Doug Brooks and Dr. Johannes Adam explain the material parameters and properties that determine the temperature of a trace, how these... [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]

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]

Designing the Signal Return Path

When designing a PCB, the signal routing and its return are critical to the circuit working properly. Great care is usually given to routing the signals, but often the return portion is the last... [more]
