Low voltage precharge CMOS logic

Abstract

In this paper we present ultra low voltage low power CMOS logic. The low power gate may be configured or recharged to high speed or low power compared to a complementary inverter. The low power logic presented in this paper resembles precharge CMOS logic. For a low supply voltage a sleep mode configuration is presented which may reduce the power consumption to less than 0.5% of a complementary inverter. A sleep mode configuration of the low power logic is presented and a keeper function is added to increase the noise margin and reduce the static power consumption. Simulated data for a STM 90nm process using Spectre simulator provided by Cadence is included.
