Abstract
We propose a Current Mirror Evaluation Logic (CMEL) and show (for 0.13µm technology) that this new logic achieves 28-to-47% (10-to-27%) delay reduction against high fan-in single/multi-stage domino (conditional keeper domino [1]) OR gates at an affordable power and area penalty. In addition, CMEL shows 54-to-95% (18-to- 45%) delay reduction against high fan-in single stage (multi-stage) domino AND gates. Consequently, the proposed logic achieves high performance and noise immunity for high fan-in dynamic AND and OR gates, respectively, compared to that of conventional domino and conditional keeper domino circuits.
