Memristive Circuit Design of Five-Person Voter Based on Memristor Ratioed Logic

Conventional CMOS-based logic circuits are approaching their limits when it comes to speed and energy consumption, so the development of new electronic components becomes critical. Memristor is a nano-structured special electronic device with the advantages of simple structure, low power consumption and easy integration. This invention supplys a new method for developing complex logic circuits. This article mainly presents the design of a five-person voter circuit. The OR/AND logic can be accomplished by varying the polarity of two parallel memristors. On the basis of the two logic circuits, adder and comparator are constructed. Further, based on the adder and comparator, a five-person voter is implemented. The correctness and rationality of the five-person voter based on MRL are confirmed via logistical analysis and simulation. Compared with the traditional logic circuits, the logic circuit designed in this paper has advantages in area cost. The realization of the five-person voter circuit further proves that the logic circuit based on memristor can be cascaded. The research results are expected to build more complex circuits, which may provide a reference for the design of other practical circuits.
