Comparison between nMOS pass transistor logic style vs. CMOS complementary cells

Abstract

This paper compares three different logic styles for implementing arbitrary Boolean functions of up to three inputs in terms of their layout area, delay and power dissipation. The three styles are nMOS pass transistor based design, NAND gate based design, and CMOS complementary logic design. Results of the comparison show that pass transistor based design is superior to NAND based design, but loses to CMOS complementary logic design.
