Advanced Low-Power Digital Circuit Techniques

Presenting a number of high performance digital circuit designs that emphasize low-power and low-voltage operation, this text shows a wide range of circuits used in current VLSI systems. Each chapter contains a brief introduction that serves as a quick background and gives the motivation behind the design. Each chapter also ends with a summary that briefly explains the contributions contained therein. Examples of circuits used in systems where low-power is important from reliability and portability points of view (such as general-purpose and DSP processors) are presented in Chapters 2, 3 and 4. Chapters 5 and 7 give examples of circuits used in systems where reliability and more system integration are the main driving forces behind lowering the power consumption. Chapter 6 gives an example of a general purpose high-performance low-power circuit design. "Advanced Low-Power Digital Circuit Techniques" is a real designer's book. It investigates alternative circuit styles, as well as architectural alternatives, and gives quantitative results for comparison in realistic technologies. Several of the circuits presented have been fabricated so that simulations can be checked.The circuits covered are the most important building blocks for many designs, so the text will be of direct use to designers. MOS designs are covered, as well as BiCMOS, and there are several novel circuits.
