Comparative Analysis of Memristor Models with a Window Function Described in LTspice

Abstract

In recent decades, memristive systems, synthesized on the basis of the fourth passive electrical element, the memristor, are developed. A memristor is a controlled resistor with memory, its resistance is nonlinearly dependent on the history of the current change in it. The application of memristor systems is wide, for example, memory devices, neuromorphic systems, neural networks, nanoelectronics devices used for various purposes. This diversity is due to the advantages of memristive systems (compactness, energy efficiency, high performance). Memristors are created using new materials and technologies. As a result, there are difficulties in their analytical and numerical modeling. The main mathematical models of memristors, their advantages and disadvantages, the possibility of implementation in LTspice are represented.
