WebJul 22, 2024 · In PCB design, ground circuits are usually designed with copper planes. Unlike signal traces, copper planes may vary in dimensions and cover a large area of the PCB. While it is still possible to obtain the impedance value of the ground plane, it isn’t feasible to do so compared to measuring the impedance of signal traces. WebIdeally, the ground plane should cover the entire PCB to ensure the current return path is always the shortest distance possible. Keep high-speed signal return currents separate from other ground currents: High-speed signals can create significant current loops that can interfere with other ground currents. To minimize this interference, it’s ...
