Abstract :
This paper demonstrates a new approach for minimizing the total of the static and the dynamic power dissipation components in a complementary metal-oxide-semiconductor (CMOS) logic network required to operate at a specified clock frequency. The algorithms presented can be used to design ultralow-power CMOS logic circuits by joint optimization of supply voltage, threshold voltage and device widths. The static, dynamic and short-circuit energy components are considered and an efficient heuristic is developed that delivers over an order of magnitude savings in power over conventional optimization methods.
