Mem-Elements Emulator Design With Experimental Validation and Its Application

Abstract

An emulator circuit of Memristor, Memcapacitor, and Meminductor commonly termed as mem-elements has been demonstrated in this article. The circuit has been realized using the technique of current mode, which provides better performance over voltage mode counterparts. The current mode analog building blocks, along with a few passive components, have been used in the presented circuit implementation. The fingerprint characteristics have been observed in both simulation and experimental results, validating the theoretical analysis. The robustness of the presented design has been supported by performing different types of analysis like process corner, temperature, and non-volatility behavior. The mem-elements emulator design has been simulated using 0.18 µm TSMC process parameter, and ± 1.2 V power supply has been used. The commercial ICs AD844 and CA3080 are used for the experimental demonstration of the proposed mem-elements design by making a prototype on a breadboard. A layout area of 4829 µm 2 , 8098 µm 2 , and 8061 µm 2 respectively is required for the Memristor, Memcapacitor, and meminductor circuit. The power consumed by the mem-elements circuit is also provided. A chaotic has been implemented using mem-elements to show the usefulness of the emulator design.

Current Conveyor Transconductance Amplifier (CCTA) based Grounded Memcapacitor Emulator

“…In [3] the proposed circuit utilizes voltage differencing current conveyor (VDCC) as an active block along with one capacitor and a memristor emulator. The memcapacitor emulator circuit proposed in [2] comprises two current conveyors, one Operational Transconductance Amplifier (OTA), two resistors, and two capacitors. The emulator circuit proposed in [1] was realized using a voltage differencing transconductance amplifier (VDTA), a memristor emulator, and a capacitor.…”

“…These devices offer various advantages as compared to voltage mode circuits such as large dynamic range, high linearity etc. CCII is considered as a fundamental block for the realization of currentmode circuits [2][3]. It is a three-terminal device as shown in figure 2.…”

“…Chua has theoretically explained that a memristor is a nonlinear device whose resistance is determined by the charge that has passed through it. Thus, it behaves like non-linear resistance with memory [1][2][3][4][5]. In 2008, scientists at Hewlett-Packard laboratories realized the first physical model of memristor using titanium dioxide (TiO2) and platinum electrodes [6][7][8][9][10][11].…”

On the Investigation of Frequency-Related Fingerprints of Meminductor/Capacitor and Their Duals Realized by Circuit Emulators

“…This is the basis for the realization of other memelement emulators. Some popular memelement emulators can be visited in [15][16][17][18][19][20][21], in which different PHL curves are shown for the realized memelements plotted in their related basic quantity plane (v-i, q-v, and ɸ-i respectively).…”

“…The different memelement emulators have been given in [17] by using ICs AD844 and AD633 to realize the memristor, meminductor, and memcapacitor, respectively. Another set of three memelement emulators to emulate the memristor, memcapacitor, and meminductor respectively, have been proposed in [18] by employing the CCIIs and OTA (Operational Transconductance Amplifier). A very important design has been proposed in [19] for the emulation of memcapacitor emulator based on a piece-wisely linear constitutive relation of memcapacitive quantities.…”
