Design of a Four-Person Voter Circuit Based on Memristor Logic

Abstract

The development of traditional CMOS-based logic circuits in terms of speed and energy consumption is approaching the limit. Memristor is a kind of bio-inspired hardware with special structure, which has the advantages of simple structure, low power consumption and easy integration. It has a good application prospect in high performance memory and neural networks. The invention of memristors provides a new way to develop more efficient logic circuits. In this paper, the memristor-based logic gates are employed to implement complex logic functions. By changing the polarity of two parallel memristors, the OR logic and AND logic can be implemented separately. By using these basic logics, adders and comparators are performed, and further, a four-person voter is designed. The feasibility of a four-person voter based on memristor logic is verified by theoretical analysis and Pspice simulation. The memristor logic circuit provides the basis for the building of more complex circuits in the future. It also provides support for the development and application of bio-inspired hardware.
