Optimal assignment of high threshold voltage for synthesizing dual threshold CMOS circuits

Development of the process technology for dual threshold (dual V _th) CMOS circuit has opened up the possibility of using it to reduce static power in low voltage high performance circuits. It has been demonstrated that by using transistors of a low threshold voltage for gates on the critical path, and by using a high threshold voltage for gates in the off-critical path it is possible to significantly reduce leakage power consumption of a circuit without performance degradation. In this paper we have a new algorithm to realize dual CMOS circuits. Our algorithm produces significantly better results for ISCAS benchmark circuits compared to reported results
