Memristor Emulator for Memristor Circuit Applications

Abstract

A memristor emulator which imitates the behavior of a TiO memristor is presented. Our emulator is built from off-theshelf solid state components. To develop real world memristor circuit applications, the emulator can be used for breadboard experiments in real time. Two or more memristor emulators can be connected in serial, in parallel, or in hybrid (serial and parallel combined) with identical or opposite polarities. With a simple change of connection, each memristor emulator can be switched between a decremental configuration or an incremental configuration. The hardware and spice simulation of the proposed emulator showed promising results that provides an alternative solution of TiO memristor model in real circuit.

Emulator Circuits and Resistive Switching Parameters of Memristor

“…Nonetheless, so as to verify the workableness of the presented structure, the SPICE simulation results are given. Kim and co-workers presented the active circuit element-based memristor emulator [38]. This circuit is also implemented on the bread board using discrete circuit elements that are ADL1116PAL for NMOS transistors, ADL1117PAL for PMOS transistors, TL082 for OPAMP, and AD633 for analog multiplier and passive elements.…”

Memcapacitor: Modeling, Analysis, and Emulators

“…Recently, a memristor emulator was introduced which emulates the behavior of the memristor using off the shelf components to use it in memristive circuits [27]. By using a similar analogy between current and charge for the resistance and the capacitor respectively, the model is developed.…”

“…The feedback voltage is given as: In Fig. 6.27, the incremental memcapacitor is emulated using a single multiplier, four opamps, resistors, capacitors, and a current controlled current source which could be implemented using the same circuit in [27]. Furthermore, the decremental memcapacitor could be implemented in the same way but without using the inverting buffer in the feedback as there is a required inversion from the active integrator.…”

Meminductor: Modeling, Analysis, and Emulators

“…Also this model is different than the previous emulator models so the emulator should be modified to fit this model. Recently, different memristor emulators were introduced showing good behavior [14,15], however, the most practical one was introduced in [16] where the authors implemented and tested the emulator experimentally. Despite the fact that …”
