Abstract

The invention discloses a secondary smooth flow control memristor analog circuit, which utilizes an analog circuit to realize the volt-ampere compact characteristic of a secondary smooth flow controlmemristor, and belongs to the technical field of circuit design. The intrinsic relation of the memristor is realized by using the design of an integrated operation circuit. Specifically, an operational amplifier is used for designing a conversion circuit to realize the equivalent conversion of the current and voltage signals; the proportional operation of an input voltage signal and an output voltage signal is realized by using an inverting proportioner, and the input and the output are in an inverting relationship; the adding operation of a plurality of input voltage signals is realized by using an inverse proportion adder, so that the input voltage signals are summed to serve as the output voltage signals with opposite polarities; an inverting integrator is used for realizing the integral operation on an input voltage signal, and a multiplication circuit is used for realizing the product operation of the two input voltage signals. The designed circuit can replace an actual secondarysmooth flow control memristor analog circuit to realize the circuit design, experiment and application related to the secondary smooth flow control memristor analog circuit, and is of great significance to the electrical characteristic research, such as the series-parallel connection with other electronic components, the practical application research, etc.

Description

technical field [0001] The invention belongs to the technical field of circuit design, in particular to a secondary smooth flow control memristor analog circuit. Background technique [0002] Based on symmetric logical relationships, Chua in 1971 predicted the existence of a fourth fundamental circuit element associated with charge and flux—the memristor, whose name derives from the historical dependence of resistance on the amount of electricity passing through it. In 1976, he further extended the memristor to the memristor system, and gave the compactness effect and frequency effect for judging the characteristic fingerprint of the memristor. These studies are limited to theoretical discussions, and physical memristors have not yet appeared. In 2008, Hewlett-Packard Labs prepared the first non-volatile nanoscale memory device, showing the characteristic fingerprint of memristors, enabling the existence of memristors to be physically verified. Subsequently, a variety of m...
