Contents I. Introduction
In the resent years, rapid innovations in the semiconductor industry and scaling of CMOS transistors have helped to maintain relatively constant power per unit area while allowing more transistors to be packed in the same chip-area. These modern high-speed and high-density systems operating at higher frequencies require quality power supply modules in order to power billions of devices contained in them. Since the noise margins have significantly reduced due to the reduction in the supply levels, the quality and performance of electronic systems can be greatly affected. Hence, designing for ensuring power integrity becomes increasingly challenging in modern electrical circuits.
