Low power design using dual threshold voltage

ABSTRACT

In this paper, we will study the reduction of static power consumption by dual threshold voltage assignment. Our goal is, under given timing constraint, to select a maximum number of gates working at high-Vth such that the total power gain is maximized. We propose an maximum independent set based slack assignment algorithm to select gates for high-Vth. The results show that our assignment algorithm can achieve about 68% improvement as compared to results without using dual Vth.
