Investigation of Power Consumption Effect of Various Memristor Emulators on a Logic Gate

Abstract

Memristor, also known as memory resistor, is considered as the fourth passive electronic element expressing the relationship between magnetic flux and electric charge. One of the most important features of the memristor is that it has low power consumption. Minimizing power consumption is an important issue in the electronic circuits. However, the fact that the memristor element was not yet fully manufactured has led researchers to design memristor-like emulator circuits. These circuits, which approximate the memristor properties, are realized by combining the other existing electronic elements. In this paper, a basic NAND logic gate is considered and the change in power consumption when using a memristor instead of the standard resistor in the gate circuit is examined. For this purpose, the NAND logic circuit was constituted for four different memristor emulators, and the power consumption values of these circuits were obtained by simulation and experiments. These values are compared with the power consumption values of NAND circuits obtained by using standard resistors equivalent to the memristor resistance. The results clearly show that the memristor gate circuits reduce power consumption compared to standard resistive gate circuits.

“…The electrical circuits consisting of various electronic elements and having the characteristics of a memcapacitor are called memcapacitor emulators. In the literature, there are many memcapacitor emulators designed for application to different electronic circuits (Babacan, 2018;Gursul, 2021). In this study, a memcapacitor emulator designed by Yeşil & Babacan (2021), one of the emulators in the literature, is considered.…”

“…The memristor produces a nonlinear relationship between the current (i) and voltage (v), where the memory effect is manifested by a characteristic pinched hysteresis loop in the voltage-current characteristics (Driscoll et al, 2010;Strukov et al, 2008). Memristor element has been used by researchers in many different areas in the literature due to its memory feature compared to standard resistance and its interesting nature (Gursul & Hamamci, 2019;Sahin et al, 2020;Yuet al, 2020;Gursul & Hamamci, 2021).…”
