On the Boundaries of the Realization of Single Input Single Element-Controlled Universal Memelement Emulator

The paper discusses in detail the inability of a circuit designer to design a single input single element-controlled universal memelement emulator. A Single input Single element-controlled universal memelement emulator would be such a configuration that can provide the realization of any of the three memelements (Memristor/Memcapacitor/Meminductor) by taking a circuit element as inductor (L), Capacitor (C) or Resistor (R) with the same input port. The analysis shows that no such circuit configuration can be built to realize such a highly flexible universal memelement emulator. It is found that by using such structures, only two ideal memelements can be realized at maximum. If these circuit structures are used to realize the remaining third memelement, then, the resulting element comes out to be a non-ideal memelement. Two circuit configurations to demonstrate this theory are also included for both charge-controlled and flux-controlled memelement emulation based on the approaches shown in this paper.

Automated summary

The paper discusses the impossibility of designing a single input single element-controlled universal memelement emulator in detail. Such a configuration would allow the realization of any of the three memelements (Memristor/Memcapacitor/Meminductor) by using a circuit element as an inductor (L), capacitor (C), or resistor (R) with the same input port. The analysis shows that it is not feasible to build a highly flexible universal memelement emulator with this kind of circuit configuration. Only two ideal memelements can be realized at most using these structures. If these circuit structures are used to realize the remaining third memelement, the resulting element becomes a non-ideal memelement. Two circuit configurations are provided to demonstrate this theory using charge-controlled and flux-controlled memelement emulation approaches.
