Comparing Time-Domain and Frequency Domain Techniques for Investigation on Charge Delivery and Power-Bus Noise for High-Speed Printed Circuit Boards

Abstract

The performance of power distribution network is critical to high-speed digital circuits in terms of both 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 as well as the frequency domain. Some of the PDN performance analysis is easier to understand when analyzed in the time domain. The effects of capacitor location, capacitor value, power/ground plane pair location within the stackup, board size, as well as dielectric material, are discussed.
