In this paper we describe a new algorithm for transistor sizing in CMOS DCVSL (Differential Cascode Voltage Switch Logic) digital circuits. Our proposed method has two different approaches with low computational burden, mathematical based and genetic algorithm based. Using our transistor sizing algorithm, we minimized the propagation delay of a DCVSL full-adder and a DCVSL XOR in 0.5 um CMOS technology. At first, the optimum sizes of these circuits were calculated to obtain the minimum propagation delay. Then the final transistor sizes were obtained by trading off speed, energy and area to meet a set of performance requirements.
