Secure and reliable communication using memristor-based chaotic circuit

Abstract

This research paper demonstrates behavior of memristor emulator circuit at various input frequencies. It is a critical circuit having a vast potential for constructing digital and analog circuits, FM-to-AM converters, filters, cellular neural networks, sensors, analog circuits, and chaotic oscillators are all designed with memristor circuits. It has some unique properties such as nonlinear behaviour, analog signal processing, adaptive and reconfigurable system, memory and state retention and also high density and low power consumption. These properties build the communication system more reliable secure and more efficient. To enhance the design of the memristor model, implementation doing using analog multiplier and operational transconductance amplifier with a constant transcoductance gain is employed. In addition to the input supply voltage frequency (f) and amplitude (Vm), the operational transconductance amplifier provides a control parameter known as the transconductance (gm). Modifications in amplitude have an impact on memory resistance, and variations in biassing voltage influence transconductance (gm) of OTA. The research shows memristor-based chaotic circuit use for secure transmission system. The operational frequency that exhibits the maximum value is 10 kilohertz, accompanied by a power dissipation of 24.1 microwatts with noise \(51.9\text{ nV}/{\text{Hz}}^{1/2}\) at room temperature. This study employs a circuit electronic design automation (EDA) tool to demonstrate the behavior of a memristor circuit under varying input conditions.
