Description

technical field [0001] The invention belongs to the technical field of circuit design and relates to a memristor simulator circuit, in particular to the design and realization of a floating voltage-controlled memristor simulator circuit. Background technique [0002] Memristor is the fourth type of circuit element in parallel with resistors, capacitors, and inductors in the circuit. It was proposed by Cai Shaotang in 1971, and the memristor was realized in HP Lab in 2008. Memristor has non-volatile and nonlinear properties, which can be applied in non-volatile memory, artificial neural network and circuit design. However, because existing memristors adopt nanotechnology, there are defects of difficulty in implementation and high cost, and memristors have not yet entered the market as an actual component. Therefore, it is of great significance to design a memristor equivalent circuit and use it to replace the actual memristor for experimental and applied research. Even if t...

Problems solved by technology

[0003] At present, although the existence of a small amount of memristor equivalent circuits has been reported, they mainly focus on the equivalent circuits of magneto-controlled memristors and charge-controlled memristors, and there is no equivalent circuit of voltage-controlled memristors. Circuits designed using voltage-controlled memristors are simpler than circuits containing magnetically controlled memristors or charge-controlled memristors, and floating memristors are more convenient to use than memristors with one end grounded
