Abstract :
The transmission function theory and research on ternary CMOS circuits are extended to quaternary CMOS circuits, whereby the CMOS design of a quaternary full adder is proposed. The circuit has advantages such as simplicity, low dissipation, and low-output impedance. It is shown that the quaternary CMOS full-adder has a simpler circuit construction (123 MOS transistors) although it may process more information. Furthermore, it can also use the carry-look-ahead technique for realizing high-speed operations
