“…In demonstrating the signal division (filtering) model, the authors replaced the resistor and capacitor in a typical double-pole, passive, RLC series circuit with a memristor and memcapacitor respectively. 15 The study used the non-linear dopant drift model of the memristor and the piecewise linear model of the memcapacitor. 16 It reports improvements in time-variability and controllability of the resulting bandpass and bandstop filters.…”

This article presents the enhancement of Legendre Optimum low pass filter (LPF) in terms of reusability and bandwidth, based on the programmable memristance of memristors. Two LPFs of the third order, operating in the MF and VHF range, and designed using the insertion loss method are presented.At 600 kHz and 110 MHz, two Knowm memristors working in the forward ion-conduction mode replace R s and R L in the filter circuit. Their conductance and therefore memristance is varied such that R off − R on decreases monotonically and∕R off − R on ∕ > 0. Results show a bandwidth enhancement of up to 540 at 600 kHz, and up to 100 at 110 MHz. A reusable, cost-effective, variable bandwidth filter is achieved from the original fixed bandwidth filter.

“…When MR and MC are applied to low and high pass filters, the amplitude-frequency and phase-frequency responses can be timely varied (Arora and Niranjan, 2017). The new band-pass filter and band-stop filter are proposed by replacing resistor and capacitor with MR and MC (Yang et al , 2018; Hong and Lian, 2015). By analyzing the transfer function, amplitude-frequency response and phase-frequency response, a time-varying model is verified.…”

Purpose The purpose of this paper is to construct a flux-controlled memcapacitor (MC) emulator without grounded restriction with the binary operation ability. The active first-order low-pass filter (LPF) and high-pass filter (HPF) circuits are constructed by replacing the capacitor with MC. Design/methodology/approach The output saturation of the active device is innovatively adopted to realize the binary operation of MC with two memcapacitance values. By applying the direct current control voltage together with the input signal, the memcapacitance can be controlled, and hence, cut-off frequency of the filters can be adjusted without changing the circuit structure. Findings Experiments and simulation results show that the new filter has good frequency selectivity. Both LPF and HPF can change the cut-off frequency by changing the positive and negative control voltage. The experimental and simulation results are in good agreement with the theoretical analysis, which proves the feasibility and validity of the emulator and the filters. Originality/value These MC emulators are simple and easy to physically fabricate, which have been increasingly used for experiment. It also provide an effective reference for device miniaturization and low power consumption.
