Automating the CMOS Gate Sizing for Reduced Power/Energy

This paper presents a new method for sizing the transistors in CMOS gates as an enabling technique for green technology. The technique utilizes an efficient feedback-based system to optimize the transistors sizes in the gates with the fanins of 2 or more. The optimized NAND2-4 gates provide nearly 65% savings in power dissipation and 58% reduction in energy consumption, as compared to their normal, uniformly sized counterparts. Power and energy savings for NOR2-4 gates are up to 8% and 38%, respectively.
