Programmable Schmitt trigger circuit based on memristor

Abstract

Because the memristor is a kind of nonlinear resistance, its resistance coefficient depends on the total charge q flowing through the element, that is, the output voltage of the memristor to the past time integral determines the resistance value of the device, according to this feature of the element can make the resistance value of the memristor realize programmable calculation, and then improve the performance of the circuit parameters. In this paper, we design a programmable memristor circuit by using a bipolar threshold memristor to realize the adjustable resistance value in the circuit, and apply it to the Schmidt trigger circuit. Through the memristor programming circuit to change the threshold setting voltage value of the Schmidt trigger, to achieve the controllable range of the back error, so as to achieve a better waveform integration effect.
