Review on Different Emulator memristor modelling and application

Abstract

This study presents an overview of operational transconductance amplifiers and memristor emulator circuits. In this work, many kinds of emulator circuits are investigated. Frequency and current-voltage characteristics are investigated with respect to emulation circuits. A solid-state circuit that can simulate the behaviour of a memristor. We provide the groundwork for a compact CMOS circuit that, by simulating an idealised memristor’s properties, might help close the gap between theoretical considerations and practical implementation on a chip. This circuit uses a commercially available integrated circuit to simulate the operation of a model titanium dioxide memristor. An easy-to-implement CMOS memristor emulator that makes advantage of the technology’s dynamic threshold feature. Capacitors are not required for use with this proposal. These proposals for circuits based on grounded memristor emulators have minimal static power consumption. The majority of the CMOS memristor emulator circuit is made up of a variable resistor with two terminals. The voltage that is put across these terminals determines the resistance of the variable resistor. A capacitor is responsible for controlling the value of a resistor and storing the “status” of a memristor. Resistive memristors, ferroelectric memristors, polymeric memristors, resonant-tunneling diode memristors, manganite memristors, and spintronic memristors are some of the most prevalent kinds of memristors that are used today. However, there are many more forms of memristors that are also in use. This study includes a review of memristor materials characteristics, switching processes, and prospective applications, as well as a performance comparison between several memristor emulators and a suggested memristor emulator, with the goal of assisting researchers in understanding the physical principles of the memristor and so providing a hopeful future for memristor devices. Additionally, this paper presents a memristor emulator that has been presented. Machine learning, Non-von Neumann computing, chaotic circuits, neuromorphic computing, and machine learning circuits are all areas where the memristor emulator circuit might be useful. It can be built and fabricated using typical commercial CMOS technology. The frequency range of the proposed memristor emulator has been proved to be retained for grounded setups by use of simulations of cadence.
