Skewed CMOS: Noise-immune high-performance low-power static circuit family

Abstract

In this paper, we present a noise-immune high-performance static circuit family called skewed logic. Skewed logic circuits in comparison with Domino logic have better scalability and they are more suitable for low voltage applications because of better noise margins. Skewed logic and its variations have been compared with Domino logic in terms of delay, power and dynamic noise immunity. Comparison between skewed and Domino circuits on a 0.25µm 700 MHz 16 × 16 bits pipelined multiplier shows superior properties of skewed circuits over Domino in terms of clock power dissipation and peak current consumption.
