Second generation current conveyor based capacitorless floating memristor emulator

Abstract

This article offers a novel flux controlled floating memristor emulator based on second‐generation current conveyor (CCII). The floating memristor is designed using two CCIIs, one resistor, and one PMOS transistor. The presented memristor emulator does not need external capacitance. The proposed designed circuit exhibits pinch hysteresis loops in voltage–current plane up to 2 GHz frequency. The performance of the circuit under consideration is evaluated using 180 nm CMOS technology parameter by the SPICE simulator. The circuit requires a DC power supply of ±1.2 V and exhibits a power consumption of 0.766 mW. Furthermore, the resilience of the planned circuit is assessed by examining process corner fluctuation, supply voltage variation, temperature variation, and transistor size variations. In addition, a Schmitt trigger circuit and high order filters based on designed memristor are used to confirm the operation of the proposed design at high and low frequency, respectively.
