Abstract-Emulations of memristor-family elements are very important, since their physical realizations are very difficult to achieve with recent technologies. Although some previous studies succeeded in designing memristor and memcapacitor emulators, no significant contribution towards meminductor emulator has been presented so far. The implementation of a meminductor emulator is very important, since real meminductors are not expected to appear in near future. We designed the first meminductor emulator whose inductance can be varied by an external current source without employing any memrisitve system. The principle of our architecture and its feasibility have been verified using SPICE simulation.

An efficient method to build the expandable circuits of memcapacitor (MC) emulator in various configurations is proposed using our expandable memristor (MR) emulator. Most of the previous studies succeeded in designing only a stand-alone memcapacitor emulator. In this study, the expandable architecture of memcapacitor emulator is addressed, where the connectivity and interoperability are the main concern. It is shown that the memcapacitor circuits can be built only with memristors together with a single mutator, which is connected after each input source. Examples of serial, parallel and hybrid memcapacitor circuits are demonstrated in this paper. Also, it is shown that complicated circuits of Wye (Y) and Delta (Δ) memcapacitor connections with multiple input sources can be built with the proposed memcapacitor emulator. Various simulation results showing the proper operations of the proposed mutator-based expandable memcapacitor emulators are included in this paper.
