“…Since it is of great benefit to circuit designers to be able to model the memristor, researchers have focused on the SPICE-based models and emulators in order to use the memristor-based circuits [14]. Several suitable memristor emulators [15][16][17][18][19][20][21][22][23][24][25][26][27] and materials [28][29] have been proposed for memristor-based systems.…”

Memristor-based resistive random access memory (RRAM) devices are very good competitors for next generation non-volatile crossbar memory applications. The sneak paths problem is one of the main constraints in fabricating crossbar memory devices. The one diode-one resistor (1D1R) structure design is effective for suppressing the sneak paths problem. Suitable circuit models are needed to simulate semiconductor structures. A general circuit model for memristor-based one diode-one resistor structures is proposed in this work. The Simulation Program with Integrated Circuit Emphasis (SPICE) environment was used to simulate the designed circuit. Well-known mathematical models such as those of Strukov, Biolek, Joglekar, Prodromakis and Zha were used to simulate the memristor component of the circuit. The current-voltage characteristics were obtained for different mathematical models. All results were compatible with the expected characteristics. The best fit characteristics were acquired using the Zha and Strukov models.

“…Several simple simulation program with integrated circuit emphasis models/ emulators [18][19][20][21] have been proposed to mimic the behaviour of the memristor but they are only for simulation purpose and several memristor emulator circuits have been proposed for the real-world application [11][12][13][14][15][16][17]. The circuits presented in [9,[22][23][24][25][26][27] are floating-type memristors having various active elements such as second generation current conveyor (CCII) [9,22], operational amplifier (Op-amp) [23], multiplier and Op-amp [24], operational transconductance amplifier (OTA) in [25], all the above proposed design consists of more number of active and passive components. In [26], the memristance value is electronically controllable but it consists of three OTAs and four CCIIs.…”

In this study, a high-frequency floating-type memristor emulator has been presented. The proposed emulator circuit uses a current conveyor transconductance amplifier, second generation current conveyor, three resistors and a grounded capacitor. The presented floating-type memristor can be configured in both incremental and decremental configurations and performs well up to 5 MHz. The equivalent memristor equation is verified by theoretical analysis of the proposed circuit which also includes non-ideal analysis. The theoretical proposition has been verified through personal simulation program with integrated circuit emphasis simulations using TSMC 0.25 μm complementary metal oxide semiconductor technology parameters. Moreover, non-volatility and Monte Carlo simulation have been performed to check the robustness of the circuit. The effectiveness of the presented memristor emulator design has been verified by printed circuit board prototype using commonly available integrated circuits AD844 and CA3080. The experimental results are included, which show good agreement with the theoretical and simulation results. To test the functionalities of the proposed designs, their applications as parallel and serial combinations, high-pass filter and Chua's oscillator have been presented.

“…Therefore, a replacement that behaves like a real memristor is still urgently needed to allow ordinary researchers to study memristor-based practical applications. Indeed, many memristor emulator circuits have been developed in recent years [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. For example, using a JFET to implement the required nonlinearity, a memristor emulator constructed with five operational amplifiers, a floating capacitor, a large number of resistors, and an analog multiplier is presented in [19].…”

“…In order to make it successfully emulate a floating memristor, the emulator circuit must satisfy strict parameter matching conditions. An electronically tunable memristor emulator circuit is presented in [32] and its memristance value can be controlled by changing transconductance parameters of the used OTAs.…”

A new floating emulator for the flux-controlled memristor is introduced in this paper. The proposed emulator circuit is very simple and consists of only two current feedback operational amplifiers (CFOAs), two analog multipliers, three resistors, and two capacitors. The emulator can be configured as an incremental or decremental type memristor by using an additional switch. The mathematical model of the emulator is derived to characterize its behavior. The hysteresis behavior of the emulator is discussed in detail, showing that the pinched hysteresis loops in V-plane depend not only on the amplitude-to-frequency ratio of the exciting signal but also on the time constant of the emulator circuit itself. Experimental tests are provided to validate the emulator's workability.
