“…The schematic of the circuit is shown in Figure . To avoid the use of a solid‐state memristor, we substituted it by a flux‐controlled resistor (that actually behaves as a two‐state bipolar memristor), represented inside the dotted box in Figure . This simplification ultimately yields a two‐state memcapacitor instead of a continuous transition of capacitance that would be produced by using, for example, an analog solid‐state TiO 2 memristor .…”

Summary This work provides the guidelines to design and implement an elemental memcapacitor circuit emulator based on the relation between memcapacitance and the Miller effect in voltage amplifiers. The emulator is presented theoretically in a top‐down approach, from the circuit behavior to the foundations of the constitutive equations of the memcapacitance and the electrical mutation of a memristor. Then, a practical and simple circuit implementation is demonstrated by SPICE computer simulations, circumventing the solid‐state memristor by a two‐state flux‐dependent resistor, which modulates the gain of the amplifier in consonance to the flux of the input signal. Further electrical properties of the system are extracted from its physical implementation in a field‐programmable analog array. The work is concluded illustrating the functionality of the memcapacitor emulator to study neuromorphic applications with a long‐term potentiation example.
