Analysis of Switching Noise on Power Planes

Power delivery networks (PDNs) in modern printed circuit boards (PCBs) are usually realized using power planes. Since the planes have very low inductance, it is usually believed that such PDNs have the smallest amount of switching noise. However, in reality, the power planes can resonate. The noise...
