A Flux-Linkage Coupled Memristor Analog Circuit with Adjustable Coupling Coefficient

Abstract

The invention discloses a magnetic chain coupling type memristor analog circuit with an adjustable coupling coefficient. The magnetic chain coupling type memristor analog circuit comprises two memristor simulators and a coupling resistor, wherein the memristor simulator is a magnetic chain control type memristor simulator, and the coupling resistor is a sliding resistor with continuously smooth adjustable level; and each memristor simulator comprises two suspension interfaces and at least one coupling interface, and access a variable directly proportional to an equivalent magnetic chain signal square value of the other memristor simulator through the coupling interface. The magnetic chain coupling type memristor analog circuit can not only express the dynamics and stable state properties of the single memristor, but also can simulate the magnetic chain coupling relation between more than two memristors, so as to research the magnetic chain coupling type memristor analog circuit from experiments and the characteristics of a series parallel dynamic circuit of other circuit elements; and the magnetic chain coupling type memristor analog circuit can be easily expanded to a multi-magnetic chain coupling type memristor analog circuit to replace the common resistors for application in the design and development of non-volatile memorys, neural network feedback systems and logic operation and other novel circuits and function circuits.

Description

technical field [0001] The invention relates to a magnetic linkage coupled memristor analog circuit with adjustable coupling coefficient, which is composed of three active devices including a transconductance operational amplifier, an analog multiplier and an operational amplifier, and several circuit components such as resistors and capacitors. Background technique [0002] In 1976, Leon Chua and Sung Mo Kang, based on the relationship between the four variables of voltage, current, charge and flux linkage, proposed that there is a fourth circuit component in addition to resistance, inductance and capacitance, and named it memristor . It was not until 2008 that Hewlett-Packard Labs successfully developed nanoscale memristive components based on titanium dioxide thin films that research on memristors attracted widespread attention from scholars. It is a two-port passive nonlinear dynamic component with memory characteristics. The memristor value of the memristor is not a fi...
