<p>This work proposes a grounded and floating memristor using a voltage differencing buffered amplifier and one grounded MOS-Cap. The proposed memristor emulator can be utilized in both decremental and incremental configurations by slightly modifying the circuits. The proposed memristor emulators are simpler in design than most of the available memristor emulator designs in the literature. In this study, the pinched hysteresis loops are maintained up to a 5 MHz frequency. The proposed circuit includes essential features such as low power consumption, no passive component usage, and utilizes a limited number of transistors. The performance analysis of the proposed memristor emulator is ascertained with GPDK 45nm complementary metal-oxide-semiconductor process technology in the Cadence Virtuoso tool and indicates more promising performance than previously introduced emulators. Moreover, this work investigates the usage of memristive components in diverse application domains, such as binary-weighted digital to analog converters, bandpass filters, and associative learning. Further, post-layout simulations and their detailed comparison with earlier designs are carried out, representing the merits of the proposed memristors. </p>

“…Analog circuit emulators for memristors simulate the characteristics of memristors by using basic circuit components, such as operational amplifiers, voltage multiplexers, resistors, and capacitors. [6][7][8][9] The analog circuit emulator builds modeling equations based on the memristor's experimental data, which match the physical properties of the memristor. Digital emulators also attract many researchers due to their small area, hardware flexibility, reconfigurability, and ease of programming and control.…”

Compared with the traditional memristor, it's more significant to research the multivalued memristor in improving the stability and reliability of memristive neural networks. Developing some multivalued memristor emulators is highly attractive since the fabrication and integration of the memristor are not mature at present. This work presents a behavioral‐level model of a general multivalued memristor FPGA that exhibits continuous or discrete behavior, similar to electrochemical metallization memories. The proposed solution has been successfully synthesized and verified on a Xilinx ZYNQ‐7000 FPGA XQ7Z020 with less than 1% hardware utilization. Additionally, to test the synaptic function of the memristor model in artificial neural networks, this paper constructs a quantized artificial neural network based on eight‐valued memristors in FPGA. In the training of the neural network, the pixel values of the images and the network weights are quantized and then mapped to the input voltage and conductance respectively of the memristor during the forward propagation. The experimental results show that the memristive network circuit achieves 92.8% recognition accuracy for 10,000 MNIST images.

“…These emulators uses various analog building blocks (ABB) such as CCII [7][8], OTA [9][10][11], VDCC [12], CBTA [13], CCTA [14], VDBA [15], VDTA [16][17], DVCCTA [18], CFTA [19] etc. Many memristor emulators were presented using mixed ABB [20][21][22][23][24]. Along with ABB, these emulators use a few passive elements like R and C. Many proposed emulators also use analog multipliers along with ABB and passive elements.…”

In this article, a flux-controlled memristor emulator is proposed. The proposed memristor emulator is designed using a single DVCC, three MOSFETs, and one capacitor. Among three MOSFETs, two MOS is used to create an active resistor, and one MOS is used to generate the multiplication factor required for the memristor emulator. The proposed emulator work for both incremental and decremental configurations. PSpice simulation with 180 nm CMOS technology is performed to validate the proposed memristor emulator. The proposed design operates up to 100 MHz frequency. The proposed memristor emulator is experimentally verified using AD844AN and CD4007 ICs. A high pass filter is implemented using the emulator for validating the resistive property of the proposed memristor emulator.
