“…Saigusa et al 31 demonstrated that amoeba-like cells possess the ability to adapt and modify their actions in anticipation of forthcoming stimuli. Several studies in the literature [32][33][34][35] have utilized serial RLC circuits with memory elements to electrically replicate this phenomenon. In order to demonstrate the memory properties of the proposed memcapacitor emulator, an RCL circuit has been established that simulates the relationship between amoeba's locomotive speed and temperature as shown in Figure 8.…”

SummaryIn this paper, a new floating memcapacitor emulator that consists of a single multiplier and only four transistors without using passive elements is proposed. While two of these transistors work as MOS capacitors, two of them are used to provide transconductance gain. Moreover, the proposed memcapacitor operates at high frequencies thanks to having simple structures. Furthermore, fix and variable parts of memcapacitance can be tuned electronically by changing DC bias voltages. In order to investigate the performance of the proposed memcapacitor, simulation results are given for different operating frequencies, radical temperature changes, memory effects, and Monte Carlo analysis. Moreover, to confirm the practical realization of the proposed memcapacitor, the proposed floating memcapacitor is implemented by using commercial devices as AD633, ALD1106, and ALD1107. Experimental results of the proposed circuit are given for different operating frequencies and DC supply voltages. Also, a memcapacitor‐based circuit that emulates the relationship between the amoeba's locomotive speed and temperature is given as an application of the proposed memcapacitor. The results for the proposed memcapacitor are in good agreement with theoretical data.

This work presents a flux-controlled memristor structure employing a Current-Controlled Current Differencing Transconductance Amplifier (CCCDTA) with a grounded capacitor. The proposed emulator’s invariant and variant parts can be safely adjustable, showing promising characteristics of up to 1.5 MHz operating frequency. Furthermore, there is no need for an additional circuit, switching mechanism or changing the circuit topology for the changing of operation modes. To justify the performance of the emulator with incremental and decremental mode operations, a Monte Carlo and temperature analysis are validated using TSMC 0.18 µm technology under a symmetrical supply voltage of ±0.9 V. Furthermore, the workability of the proposed circuit is tested with commercial elements such as ALD1116, AD844 and LM13700. When compared with other studies, the presented emulator circuit demonstrates promising performance in various features.

“…Additionally, it necessitated one resistor and two capacitors [19]. Petrovic [20] expanded the concept of the voltage difference transconductance amplifier (VDTA) to a multiple-output VDTA (MO-VDTA) and proposed an MIE employing a single MO-VDTA, while a compact emulator structure which realizes the behavior of a floating meminductor and memristor employing a single VDIBA (a voltage differencing inverted buffered amplifier) and a dual-output OTA was proposed in [21].…”

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.
