A Practical Implementation of a Floating Memristor-Less Meminductor Emulator

A meminductor, a nonlinear two-terminal device with memory and energy storage ability, is generalized on the basis of the conception of a memristor. To date, the meminductor is commonly unavailable; therefore, it is of great significance to build a meminductor emulator in hardware. In this brief, a practical floating flux-controlled meminductor emulator is designed without using a memristor. Moreover, it possesses floating terminals and a variable structure that allow the designers to alter the nonlinear flux-controlled function only via utilization of fewer electronic components. Frequency-dependent current-flux dynamics of this meminductor have been captured in the experiment, which convincingly confirms the validity of this emulator. Finally, the experimental errors existing in the hardware circuit are analyzed. All the analysis results manifest that this newly proposed floating emulator can be operated as a floating meminductor and applied in the analog circuit design.
