摘要

我们研究了通过双阈值电压分配来降低静态功耗。我们的目标是，在给定的时间约束下，选择在高电压下工作的栅极的最大数量，从而使总功率增益最大化。我们提出了一种基于最大独立集的松弛分配算法来选择高v值的门。结果表明，与不使用双Vth的结果相比，我们的分配算法可以实现约68%的改进。

Low power design using dual threshold voltage

We 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 a 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.
