64-bit low threshold voltage high-speed conditional carry adder by complementary pass-transistor logic

Abstract

A 64-bit low threshold voltage conditional carry adder using complementary pass-transistor logic for low-voltage and high-speed application was presented. The improved conditional sum addition rule can reduce the number of internal nodes and multiplexers in the adder design. And reducing the threshold voltage increases the speed of operation. Thus, a low… (More)
