A novel meminductor emulator based on analog circuits

Abstract

Meminductor, a nonlinear device with memory ability and controllable meminductance, was generalized on the basis of the conception of memristor. Currently, meminductor is still unavailable on the market. Therefore, in order to investigate its properties and potential application, designing electronic emulator is of significant importance. In this paper, a flux-controlled memristive emulator using ligh-dependent resistor (LDR) is proposed and the mutator for transferring memristor into a flux controlled meminductor is described, of which the realization is on the basis of two current conveyor chips and operational amplifiers. Results of Pspice simulation and hardware experiments indicate that the current-flux characteristic of the meminductor is a frequency-dependent pinched loop, like an inclined number “8”. To confirm the effectiveness and correctness, the proposed emulator is analyzed theoretically and tested experimentally as it is connected in an RLMC series circuit. The dynamic behaviors of the RLMC circuit are analyzed and observed. All the results manifest that this newly proposed emulator is capable of simulating a nonlinear meminductor and can be applied to the analog circuit design.
