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 of a memcapacitor emulator. The circuit includes an integrated operational amplifier U1 and a multiplier U2. The integrated operational amplifier U1 is used to realize integrator operation, inverting amplifier operation and adder operation; the integrator is used to realize input Integrate the signal, and then realize the inverting amplification of the integral signal through the first inverting amplifier, input the inverting amplified signal to the multiplier U2, the other end of the multiplier U2 is connected to the input signal, and the multiplier U2 is used to realize the signal multiplication; the input signal is then passed through the second inverting amplifier to achieve inversion amplification of the input signal, and the signal after inversion and amplification is input to the adder, and at the same time, the signal multiplied by the multiplier U2 is input to the adder, and the addition The device is used to realize the summation operation of the signal, and finally obtain the output charge. The invention only includes one integrated operational amplifier and one multiplier, and has a simple structure.

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 ...
