New grounded passive elements-based external multiplier-less memelement emulator to realize the floating meminductor and memristor

A novel memelement emulator configuration has been reported in the presented work. This proposed configuration can be used to realize the function of a floating meminductor as well as the memristor element through proper selection of employed passive elements. The presented emulator circuit is based on MVDCC (modified VDCC) and OTA, which are CMOS implemented electronically tunable ABBs (Active Building Blocks). The designed circuit employs only two ABBs and three grounded passive elements. As per the knowledge of the authors, no such emulation configuration with a floating architecture has been reported so far, which can realize the behaviour of two mem-elements without the use of any external multiplier IC/circuitry, passive inductor or mutation through any externally employed memelement. It can be considered as a notable design feature along with its other advantages like electronically/resistively tunable emulated response and use of only grounded passive elements. Moreover, proposed circuit has been investigated for the consideration of non-idealities and different port parasitics of employed blocks. For the verification purpose, PSPICE simulation environment with CMOS 0.18 µm TSMC technology parameters, has been selected. The functioning of the realized meminductive and memristive behaviour has also been verified through the application example circuits designed using developed emulator circuit. Afterwards, the commercial IC based realization of the proposed emulator circuit has been shown and experimental results are discussed.
