Opis

This book presents an in-depth treatment of various power reduction and speed enhancement techniques based on multiple supply and threshold voltages. A detailed discussion of the sources of power consumption in CMOS circuits will be provided whilst focusing primarily on identifying the mechanisms by which sub-threshold and gate oxide leakage currents are generated. The authors present a comprehensive review of state-of-the-art dynamic, static supply and threshold voltage scaling techniques and discuss the pros and cons of supply and threshold voltage scaling techniques.

For more than four decades, the scaling of semiconductor process technologies has revolutionized electronics applications, with complementary metal–oxide–semiconductor (CMOS) technology dominating the semiconductor industry in recent years. The scaling of CMOS technology coupled with advanced in circuits structures and microarchitectures have significantly increased the performance of integrated circuits (ICs). The side–effects of these performance and functional enhancements have traditionally been increased design complexity, greater power consumption, and higher fabrication cost. Multi–voltage design now plays a crucial role in allowing the industry to meet the growing customer demand for high–performance ICs offering a wider variety of applications at a reduced cost.

Multi–voltage CMOS Circuit Design provides an in–depth analysis of several new techniques for designing low–power and high–speed ICs with particular emphasis on the approaches based on using multiple supply and threshold voltages. Starting with a detailed overview of the evolution of IC technologies, the authors go on to examine:

• the sources of power consumption in CMOS ICs;
• the mechanism that produce sub–threshold and gate oxide leakage currents;
• advanced supply and threshold voltage scaling techniques for lowering power consumption and enhancing reliability;
• energy–efficient monolithic DC–DC conversion techniques for low voltage applications such as microprocessors;
• in–depth evaluation of the potential of emerging multi–voltage circuit techniques for sustaining the scaling trends of CMOS technologies.

A valuable text for researches and electronic engineers working in the semiconductor technology industry, Multi–voltage CMOS Circuit Design is also a useful reference for graduate students taking courses on advanced topics in IC design.
