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

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.
