New Multiplier-Less Compact Tunable Charge-Controlled Memelement Emulator Using Grounded Passive Elements

Unlike the memristor element, the unavailability of any physical architectures for other memelements (memcapacitor and meminductor) has enhanced the significance of emulation of these elements through analogue circuit implementation. The proposed work aims to present a charge-controlled memelement emulator using a VDCC (voltage differencing current conveyor) and an OTA (operational transconductance Amplifier) with grounded passive elements. The developed emulator can be used to implement the behaviour of memristor and memcapacitor elements through the proper selection of passive elements. The proposed emulator circuit offers the advantage of adjustability of realized behaviour electronically and through employed passive elements as well. In the open research repertoire, the presented memelement emulator is the most optimized as compared to any other emulator ever reported for the realization of charge-dependent dual memelement functions with single-circuit architecture. It is due to the non-employment of any external memristor or bulky passive inductor and no use of any analogue multiplier in the circuit structure. The performance of the circuit has been checked through PSPICE-generated simulations for the use of 0.18um CMOS technology. The paper also discusses the application of realized memcapacitor in the modelling of Amoeba behaviour, and the results have been presented. We have also shown the commercial IC-based realization of the proposed memelement emulator and discussed the generated results through macro-model-based simulations as well as experimental.
