A Novel MTCMOS Stacking Approach to Reduce Mode Transition Energy and Leakage Current in CMOS Full Adder Circuit

摘要

A novel stacking MTCMOS circuit is proposed and their mathematical analysis is performed. The proposed circuit is simulated and performance parameters like leakage current, static energy, and mode transition energy are calculated. Results show that the proposed technique minimizes the leakage current and static energy dissipation by more than 80% as compared to the conventional MTCMOS circuit. Simulation is also performed to calculate mode transition energy dissipation. Results show that, when the same input is applied to all the inputs of full adder, the average reduction in mode transition energy is around 27%.
