“…These MREs has numerous important applications in signal processing circuits like oscillators, filters, programmable analog circuits, A/D and D/A convertors, neuromorphic systems, chaotic circuits [10]- [53] have been extensively dealt with. Apart from that MREs can further be converted to Meminductor and Memcapacitor elements which can result into further more applications [54]- [55]. It can be concluded from the survey of existing literature of memristors [8]- [49] that there is no MRE available in open literature which is low power, more stable and works at relatively high frequencies without using biasing and utilizes less number of active or passive elements based on only MOSFET.…”

A new proposition of passive (no external DC bias) memristor emulator (MRE) utilizing DTMOS technique which consists of four MOSFETs and a capacitor has been presented. The proposed MRE exhibits high operating frequency (∼ 500MHz), zero static power and shows incremental behavior. The conventional mathematical equation of MRE has been derived considering the second-order effects of all the MOSFETs utilized. The proposed circuit has been simulated by the Cadence Virtuoso (IC617) spectre tool using 180 nm technology parameters. The layout occupies 1305µm 2 area. The experimental verification has been carried out utilizing ALD1116 and ALD1117 dual N-channel and P-channel MOSFET arrays to demonstrate the practical viability. Finally, different possible applications namely; analog filters, oscillators (simple and chaotic), Schmitt trigger, Amoeba learning have been realized using proposed MRE to show its neuromorphic capability. Also, new logical AND & OR and NOT circuit configurations have been designed using proposed MRE.

“…The performance of this floating memcapacitor circuit is evaluated through both simulation and experimental results; however, it lacks electronic tunability. Ananda et al proposed a floating memcapacitor consisting of two OTAs, one unity gain amplifier (UGA), and two MOS capacitors in [30]. In their more recent work in 2023 [33], Ananda et al introduced a floating memcapacitor circuit employing one voltage difference transconductance amplifier (VDTA), one OTA, one buffer, and four passive elements.…”

“…In their more recent work in 2023 [33], Ananda et al introduced a floating memcapacitor circuit employing one voltage difference transconductance amplifier (VDTA), one OTA, one buffer, and four passive elements. The maximum operating frequencies of these circuits [30], [33] are 1.2 MHz and 24 MHz, respectively. It is worth mentioning that the number of active and passive elements in the aforementioned floating memcapacitors exceeds those utilized in the memcapacitor proposed in this paper.…”

This paper introduces two novel emulator circuits that employ a single active block. The first circuit utilizes a Voltage Differencing Transconductance Amplifier (VDTA) to emulate the behavior of a floating/grounded incremental/decremental flux-controlled meminductor. The second circuit, based on a Voltage Differencing Current Conveyor (VDCC), emulates the characteristics of memcapacitance. Both emulation circuits are constructed using capacitors as the only type of grounded passive element. Notably, these circuits possess electronic tunability, enabling control over the realized inverse meminductance/memcapacitance. The theoretical analysis of the proposed emulators includes an investigation into potential non-idealities and parasitic effects. By carefully selecting the passive circuit elements, efforts were made to minimize the impact of these unwanted effects. In comparison to existing designs documented in the literature, the proposed circuits demonstrate remarkable simplicity. Additionally, they exhibit wide frequency operability (up to 50 MHz) and successfully pass the non-volatility test. Simulation results conducted using 0.18 μm CMOS technology and a ±0.9 V supply voltage align closely with the theoretical predictions. Furthermore, Monte Carlo simulations and corner analysis are employed to evaluate the circuit's robustness. To validate the feasibility of the proposed solution, experimental tests are performed using commercially available components.

“…Given the anticipation of a delay in the commercial availability of meminductors and memcapacitors, researchers have focused on developing various SPICE models [6][7][8] and emulator circuits [9][10][11][12][13][14][15][16][17][18][19][20][21] to explore the complexities of these devices' dynamics. To replicate the behaviors of meminductive and memcapacitive elements, investigators have designed mutator circuits capable of transforming memristors into either meminductive or memcapacitive entities [9,10].…”

This paper introduces a novel circuit design for a memcapacitance emulator, employing a single Voltage Differencing Current Conveyor (VDCC) as its core element. The emulator circuit has been intricately designed, employing only capacitors as grounded passive components. One remarkable aspect of these circuits is their inherent electronic tunability, allowing for precise control of the achieved inverse memcapacitance. The theoretical analysis of the emulator includes a comprehensive examination of potential non-idealities and parasitic influences. Careful selection of passive circuit elements has been made to minimize the impact of these undesirable effects. In contrast to extant designs cataloged in the existing literature, the presented circuitry manifests remarkable simplicity in its configuration. Furthermore, it exhibits a wide operational frequency range, extending up to 50MHz, and effectively clears the non-volatility criterion. To substantiate the efficacy of the devised circuits, comprehensive LTSpice simulations have been conducted, employing a 0.18 μm TSMC process parameter and a power supply of ±0.9 V. These simulations provide robust evidence of the emulator’s performance, reaffirming the feasibility and practicality of the proposed approach in the domain of memcapacitance emulation.
