Single Active Block-Based Emulators for Electronically Controllable Floating Meminductors and Memcapacitors

. This paper introduces two novel emulator circuits that employ a single active block. The first circuit utilizes a Voltage Differencing Transconductance Amplifier (VDTA) to emulate the behavior of a floating/grounded incremental/decremental flux-controlled meminductor. The second circuit, based on a Voltage Differencing Current Conveyor (VDCC), emulates the characteristics of mem-capacitance. Both emulation circuits are constructed using capacitors as the only type of grounded passive element. Notably, these circuits possess electronic tunability, enabling control over the realized inverse meminduct-ance/memcapacitance. The theoretical analysis of the proposed emulators includes an investigation into potential non-idealities and parasitic effects. By carefully selecting the passive circuit elements, efforts were made to minimize the impact of these unwanted effects. In comparison to existing designs documented in the literature, the proposed circuits demonstrate remarkable simplicity. Additionally, they exhibit wide frequency operability (up to 50 MHz) and successfully pass the non-volatility test. Simulation results conducted using 0.18 μm CMOS technology and a ±0.9 V supply voltage align closely with the theoretical predictions. Furthermore, Monte Carlo simulations and corner analysis are employed to evaluate the circuit's robustness. To validate the feasibility of the proposed solution, experimental tests are performed using commercially available components.
