摘　　要：近年来,物联网和移动互联网为代表的应用芯片提出了越来越高的功耗要求。降低工作电压是降低功耗的有效方法,但是随着电压的降低,电路的性能也会急剧下降。针对这一问题,本文运用AOCV的时序分析方法,使得电路设计在保证性能的基础上,最大程度地降低工作电压。在先进工艺下,运用AOCV方法能够使得工作电压由1.05 V降为1 V左右,在典型工艺角下的功耗得到了有效降低,同时保证了电路的速度和时序要求。In recent years, power consumption of mobile processors becomes more severe in the application of wireless sensor internet and mobile internet. Reducing supply voltage is an efficient means to lower power consumption, but with supply voltage＇s decreasing, the circuit will be badly-behaved. In order to solve this problem, this article applies AOCV in timing analysis to reduce supply voltage as lowest besides ensuring the performance of circuit. In advanced technology, the application of AOCV can reduce supply voltage from 1.05V to about 1V, and efficiently lower power consumption in typical corner, meanwhile the circuit meet the requirements of speed and timing.
