The performance of a power distribution network is critical to high-speed digital circuits in terms of signal integrity and radiated emission. This paper studies charge delivery of a power distribution network, as well as power bus noise resulting from device switching, in the time domain. The effects of capacitor location, power/ground plane pair, board size, and dielectric material are discussed.
