Eight-Person Voter Implementation Based on Hewlett-Packard Memristor

Abstract

The logic function based on memristor has been proved and can be applied to the future large scale integrated circuits. In this paper, we use logic circuit based on memristor to realize the function of eight-person voter. The basic logic circuit designed in this paper is consisted of two Hewlett-Packard memristors in series connection and an operational amplifier. Operational amplifiers are used to regulate the output voltages to meet the requirements of the input signals in the next stage circuits. The adder, binary comparator and multi-input logic gate are realized by using the designed logic circuit. Full adders, binary comparators and multi-input logic gates are combined into eight-person voter circuit. Theoretical analysis and spice simulation results verify the feasibility of the circuit under different cases. This method is expected to be applied to more complex voter logic circuits based on memristor.
