Abstract

In this paper, single-rail and dual-rail mixed pass-transistorlogic (PTL) and static CMOS circuits are presented.The circuits were synthesized using a genetic algorithmthat determines the best mixture of PTL and static cellsbased on area and power. The mixed PTL/Static circuits usingthe proposed method are compared with their static counterpartssynthesized using a commercial logic synthesis toolin terms of area, delay and power in a 0.13µm floating-body partailly depleted silicon-on-insulator (SOI) and a 0.13µmbulk CMOS technologies. Our experimental results on benchmarkcircuits from a commercial microprocessor indicatesthat the proposed mixed PTL/Static circuits in both SOI andbulk CMOS technology outperforms their static counterpartsin power consumption and/or performance.
