Abstract

This paper explores the characteristics of Monotonic-Static CMOS and its potential applications in gate leakage reduction in a hypothetical 22nm Bulk-Si technology with significant gate leakage currents. Using test circuits consisting of NAND and NOR logic gates, we performed a comparison among static, monotonic static and domino logic in terms of various properties including power, delay, noise margin and area. Comparisons were done over a wide range of possible transistor widths to fully characterize the tradeoffs for each circuit type. Experimental results show that MS-CMOS has potential advantages in terms of stand-by power, evaluation speed and noise margin in such a technology.
