Design of Memristor with Hard-Switching Behavior Employing only One CCCII and One Capacitor

In this paper, we present second generation current-controlled conveyor (CCCII)-based simple memristor circuit which exhibits a hard-switching voltage-current relationship. The proposed memristor circuit contains only single CCCII and single grounded capacitor that are attractive for the integrated circuit designers. The proposed memristor emulator has four main advantages: hard-switching behavior, not utilizing multiplier circuit, biasing current or voltage source (excluding DC current or voltage source), and being free of body effect for all transistors. Cadence Spectre Analog Environment with TSMC 0.18μm process parameters is used for all simulations. The memristive chip occupies only 81.85μm×87.76μm area. All simulation results are presented to demonstrate the performance of the proposed circuit by changing some parameters such as frequency, temperature, DC power supply voltages and process variations. Also, the robust performance of the proposed memristor is confirmed via Monte Carlo simulations. The simulation results for designed memristor are in accordance with theoretical memristive behavior. © 2021 World Scientific Publishing Company.
