Low power domino logic circuits in deep-submicron technology using CMOS

Abstract

Leakage power and propagation delay are the two major challenges in designing CMOS VLSI circuits, in deep sub-micron technology. This paper proposes a novel technique: Foot Driven Stack Transistor Domino Logic (FDSTDL) for designing CMOS domino logic gates for the reduction in leakage power and improved noise performance. Two, four, eight and sixteen input OR gates are designed using existing and proposed techniques. These logic gates are simulated on the PTM 32 nm node using HSPICE (Level = 54) in CMOS technology at a clock frequency of 100 MHz. Simulation results are compared based on power consumption, propagation delay and unity noise gain. Simulation results show that proposed domino technique has a maximum power reduction of 59.47% as compared to the CSK-DL technique and maximum delay reduction of 44.6% as compared to the M-HSCD technique in CMOS technology.
