Problems solved by technology

At present, although a small number of memcapacitor simulator models have been reported, they all use piecewise linear, quadratic or cubic nonlinear functions as their mathematical models, which are quite different from the characteristics of memcapacitors under nanostructures, making it difficult to accurately simulate Properties of Real Memory Containers

Abstract

The invention discloses a circuit for a memory capacitor simulator. The circuit comprises an integrated operational amplifier U1 and a multiplying unit U2, wherein the integrated operational amplifier U1 is used for implementing integrator operation, inverting amplifier operation and adder operation; the integrator is used for implementing integration of an input signal, implementing inverting amplification of an integrated signal through the first inverting amplifier, and inputting the signal being subjected to the inverting amplification to the multiplying unit U2; the other end of the multiplying unit U2 is connected with the input signal; the multiplying unit U2 is used for implementing multiplication of signals; the input signal is subjected to inverting amplification through the second inverting amplifier; the signal being subjected to the inverting amplifier is input into the adder; meanwhile, the signals multiplied by the multiplying unit U2 are input into the adder; and the adder is used for implementing summation operation of the signals in order to obtain an output charge quality finally. Only one integrated operational amplifier and one multiplying unit are arranged, so that the structure is simple.

Description

technical field [0001] The invention belongs to the technical field of circuit design, and relates to a memcapacitor simulator circuit, in particular to an analog emulation circuit for realizing the memcapacitor voltage-charge relationship. Background technique [0002] Memcapacitors are another memory element following the fourth new type of circuit element, the memristor. Such devices have nanostructure and memory properties, can store information without power supply, and can be applied in fields such as non-volatile memory and artificial neural network. At present, only several mathematical models of memcaptors have been proposed, and actual physical devices have not yet been realized. In order to study the memcaptor in advance, it is important to design a memcaptor simulator. At present, although a small number of memcapacitor simulator models have been reported, they all use piecewise linear, quadratic or cubic nonlinear functions as their mathematical models, which ...
