“…Memristor emulators can be divided into two types according to their structures: floating memristors [3][4][5][6][7][8][9][10][11][12][13] and grounded memristors [14][15][16][17][18][19][20][21][22][23][24], with only certain memristor emulator circuits being suitable for high frequencies in the order of megahertz (MHz) [4,5,7,10,16,17,23,24]. Some of them can operate with a variable configuration, as one of the solutions proposed here, meaning that it is possible to emulate grounded or floating type of memristor with the same circuits [25][26][27].…”

“…Activecircuit elements provide advantages in designing complex and nonlinear circuit-element patterns. For this reason, various activecircuit-element-based memristor circuits can be found in the literature based on operational amplifier (OpAmp) [3], secondgeneration current conveyor (CCII) [6,8,12,14,21,22], differential difference CCs (DDCC) [5], current backward transconductance amplifier (CBTA) [18], operational transconductance amplifier (OTA) [9,11,15,19,25] differential voltage-CC transconductance amplifier (DVCCTA) [17], currentfeedback OpAmp (CFOA) [13,20,26]. Floating memristor emulators using one CCTA, one CCII and few passive elements have been proposed in [4], while the circuits [27] are based on only one CCTA.…”

This study proposes two new emulator circuits of floating (grounded) flux-controlled incremental/decremental memristor, based on modified z-copy current-voltage differencing transconductance amplifier (VDTA). The circuits use only one VDTA as an active element, a single grounded capacitor and a variable number of grounded resistors, which benefit from the integrated circuit. Furthermore, it can utilise metal-oxide-semiconductor (MOS) capacitance instead of the external capacitor in the circuit. It does not consist of any multiplication circuit block to obtain non-linear behaviour of the memristor. The parameters of the proposed memristor emulator can be tuned electronically by changing the biasing current of the VDTA. Change of the transconductance gain of the VDTA provides an advantage in the form of the externally controllable memristor. Through the simulation program with integrated circuit emphasis (SPICE) simulation which was carried out on the basis of 0.18 μm complementary MOS technology and experimental results using two MAX435 commercial devices as an active element, all theoretical assumptions and conclusions were reached in different operating frequencies, the capacitance value and process corner. The simulation test results have shown that the maximum frequency is 50 MHz.

In this paper, a universal charge-controlled mem-elements (including memristor, memcapacitor, and meminductor) emulator consisting of off-the-shelf devices is proposed. With the unchanged topology of the circuit, the emulator can realize memristor, memcapacitor, and meminductor, respectively. The proposed emulation circuit has a simple mathematical relationship and is constructed with few active devices and passive components, which not only reduces the cost but also facilitates reproduction and facilitates future application research. The grounding and floating forms of the circuit are demonstrated, and Multisim circuit simulation and breadboard experiments validate the emulator's effectiveness. Furthermore, a universal mem-elements chaotic circuit is designed by using the proposed mem-elements emulator and other circuit elements, which is a deformation circuit of Chua's dual circuit. In this circuit, no matter whether the mem-element is memristor, memcapacitor, or meminductor, the chaotic circuit structure does not change, and all can generate hyper-chaos.

“…Unfortunately, for the difficulty of its fabrication, the physical memristor device is inconvenient to acquire through regular purchasing channels. For the convenience of scientific research, numerous mathematical models [13]- [15], PSpice models [16] and analog circuit emulators [17]- [20] were reported for equivalently implementing the characteristics of various memristors in the past few years. Among those, the memristive diodebridge emulator [8], [10] is greatly welcomed because of the simple structure, no grounded limitation, easy circuit access and so on.…”

Symmetry brings beauty, while asymmetry is the general law of nature. This paper reports a novel parallel-type asymmetric memristive diode-bridge (AMDB) emulator, which is implemented by an unbalance diode-bridge linked with a RC filter. Following the voltage constraints of the unbalance diodebridge, the mathematical model of the parallel-type AMDB emulator is established. Thereafter, the asymmetric property of the hysteresis loops is demonstrated by the numerical simulations and confirmed by the hardware experiments. Furthermore, by importing the parallel-type AMDB emulator into the classical Chua's circuit, a novel memristive Chua's circuit is proposed, so that the asymmetric double-scroll chaotic attractor, asymmetric coexisting single-scroll chaotic attractors, and asymmetric coexisting limit cycles can be revealed herein. The parallel-type AMDB emulator enriches the types of memristor emulators and it can mimic the asymmetric property of the physical memristor device.
