DC Sensing Return Current in Mixed Signal PCBs

DC Sensing Return Current in Mixed Signal PCBs

A common high-speed PCB design rule is to track the return current path of signals. In reality, this is much easier said than done, as the return paths for fast digital signals and even medium-frequency analog signals are largely confined beneath the traces. At very low frequencies or under direct current (DC), the return path … Read more
