Dual Threshold Voltage Domino Logic Synthesis for High Performance with Noise and Power Constraint

We introduce a new dual threshold voltage technique for domino logic. Since domino logic is much more sensitive to noise, noise margins have to be taken into account when applying dual threshold voltages to domino logic. To guarantee the signal integrity in domino logic, we carefully consider the effect of transistor sizing and threshold voltage selection. For optimal design, tradeoffs need to be made among noise margin, power, and performance. Based on the characteristics of each logic gate, we propose noise and power constrained domino logic synthesis for high performance. ISCAS85 benchmark results show that performance can be improved up to 18.62% with 2% active power increase, while maintaining noise margin.
