A Flux-Controlled Memristor Equivalent Implementation Circuit Based On Single-Phase Diode Rectifier

A simple diode-based circuit, which consists of two single-phase diode rectifiers, and can be considered as an equivalent implementation circuit of a memristor, is constructed in this paper, According to the theoretical analysis, the input port admittance of the proposed circuit conforms to the definition of a flux-controlled memristive system. Simulations and experimental results further show that, the proposed circuit has a voltampere characteristic curve at the input port with an oblique "8" shape, which is unique to the memristor. Unlike those memristor equivalent circuits based on integrated operational amplifiers that handle electric signals with relatively small power, the proposed circuit can process electrical signals with larger power level in principle, since it is composed only of components such as resistors, capacitors and diodes. In addition, fewer devices are used, and the structure is simple and easy to be realized.
