Opis

This excellent survey of state-of-the-art techniques discusses the MTCMOS technology that has emerged as an increasingly popular technique to control the escalating leakage power, while maintaining high performance. It addresses the leakage problem in a number of designs for combinational, sequential, dynamic and current-steering logic.

Recenzje

From the reviews:

"This book is written for students of VLSI design and practicing circuit designers and shows how the MTCMOS technology can be used to reduce power dissipation. ... The text covers a wide range of circuit design techniques. ... Each chapter contains a brief introduction that serves as a quick background, summary that explains the contributions contained therein, and a set of additional references provided for further reading."
