Abstract

This paper studies the methodology of power integrity (PI) analysis for high speed printed circuit board (PCB) design. This involves the analysis of AC and DC characteristic of the PCB, and also the loop stability of the switch mode voltage source. Besides this, the best practices of designing a power rail with excellent fidelity are discussed in detail in this paper. The basic theory of operation of the switch mode voltage source and the concept of loop stability are also discussed. The results of simulated PI DC and AC analysis of PCB using Hyperlynx from Mentor Graphic, simulated and measured loop stability and transient response of switch mode voltage source are presented in this paper.
