A new approach for obtaining all logic gates using Chua's Circuit: Advantages and disadvantages

摘要

This paper investigates constructing a universal logic gate to perform all logic functions, namely, AND, OR, NAND, NOR, and XOR operations without changing the circuit topology. The modification that had been applied to Chua''s Circuit to construct what is called a “ChuaGate” is also investigated. The basic advantage behind our scheme is that there is no need for level conversion between logic levels at the gate terminals (direct hardwiring). A comparison between the estimated number of transistors that will be used to construct the modified Chua''s circuit with that of traditional logic gates is performed. The advantages and disadvantages are also discussed.
