Web• It is necessary in high-speed designs to have at least one complete ground plane as a reference for microstrip traces for sensitive signals. • With a complete power plane as close as possible to the ground plane, it is possible to create capacitive coupling between them to get low impedance at high frequencies. This reduces the amount
