Abstract :
This paper contributes to a better knowledge of the behaviour of conventional CMOS and CPL full-adder circuits when low voltage, low power or small power-delay products are of concern. It completes and overcomes limitations of previous studies as optimal power-delay curves, for CPL and CMOS full adders, have been constructed using an automatic sizing tool based on statistical optimization. Supply voltages of 3.3 V and 1.5 V have been considered. This study shows that full adders with minimum power consumption are accessible by using the conventional CMOS design style. As a counterpart, minimum delay full adders are obtained with CPL
