Abstract :
A circuit design style with separate logic and buffer stages is investigated for its energy and delay characteristics. Then a new numerical approach is proposed for determining the optimum transistor sizing and supply voltage according to the minimum energy-delay product as a figure of merit (FOM). The results agree perfectly with the simulation data gathered from the SPICE simulation and are much more accurate than the ones proposed in the previous works.
