Low power CMOS digital design

Abstract

This paper will first address the following issues: why a voltage transition causes power dissipation, what causes a transition, what are useful and redundant transitions, how information redundancy may reduce the number of transitions, how to statistically measure the average number of transitions (or activity). In a second part, the paper will show the incidence of scaling down the transistors on power dissipation. The third part will address the question: what is performance. Next, the fourth part will discuss complexity versus dissipation and finally glitch filtering.
