文摘

In this paper, a novel multi-valued logic gate set is designed by using only current-mode CMOS circuits. The gate set consists of min, max, inverter, literal, and cyclic operators based on a current-mode, versatile, novel threshold topology. They are shown to exhibit better static and dynamic behavior and consume less area compared to previous MVL design topologies and binary-logic counterparts. The gate circuits are investigated in terms of analog design aspects, such as mismatch and noise. The proposed topology is compared to previous topologies in terms of attainable radix and DC characteristics. A radix-8 multiplex function and a radix-8 full-adder circuit is designed to demonstrate the advantages of new current-mode multi-valued logic circuits.
