“…Gupta et al, in ref. [ 20 ], designed a current differencing transconductance amplifier (CDTA) and an OTA-based memristor emulator with an operating frequency range of 600 kHz to 2 MHz for application in the current mode filter. A differential voltage current conveyor transconductance amplifier (DVCCTA) [ 21 ] based a memristor design in incremental as well as decremental configuration and operating up to 12.8 MHz was also proposed.…”

In recent times, much-coveted memristor emulators have found their use in a variety of applications such as neuromorphic computing, analog computations, signal processing, etc. Thus, a 100 MHz flux-controlled memristor emulator is proposed in this research brief. The proposed memristor emulator is designed using a single differential voltage current conveyor (DVCC), three PMOS transistors, and one capacitor. Among three PMOS transistors, two transistors are used to implement an active resistor, and one transistor is used as the multiplier required for the necessary memristive behaviors. Through simple adjustment of the switch, the proposed emulator can be operated in incremental as well as decremental configurations. The simulations are performed using a 180 nm technology node to validate the proposed design and are experimentally verified using AD844AN and CD4007 ICs. The memristor states of the proposed emulator are perfectly retained even in the absence of external stimuli, thereby ascertaining the non-volatility behavior. The robustness of the design is further analyzed using the PVT and Monte Carlo simulations, which suggest that the circuit operation is not hindered by the mismatch and process variations. A simple neuromorphic adaptive learning circuit based on the proposed memristor is also designed as an application.

“…Further, memristor emulators are being designed using several analog building blocks such as work by Ranjan et al [9] reported grounded type of high frequency incremental/decremental memristor emulator using differential voltage current conveyor transconductance amplifier (DVCCTA) and four passive components. Yesil et al [10] proposed floating memristor based on current backward transconductance amplifier (CBTA) with two grounded capacitors, and Suchitra and Shireesh [14] presented the grounded and floating memristor employing with two active components current differential transconductance amplifier (CDTA), and operational transresistance amplifier (OTA), with one grounded capacitor. However, in some literature, a memristor emulator is designed using only OTA and some other active blocks [11]- [15], [19] with some resistors and capacitors components.…”

<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>
