Description
Summary:The speed and area advantage of domino logic circuits compared to static logic circuits makes them a favorite choice for the critical path of high performance processors. However they suffer from low noise margin. Noise is not scaling at the same rate as the supply voltage, and therefore new domino logic circuits are required to increase the noise margin. In this paper a new domino circuit is introduced. Simulations for a 3-input 180 nm AND gate shows that the noise margin can be increased by 62% with only 3% reduction in speed.
