Implementation of Memristor circuits using LTspice
Memristor as a fourth fundamental circuit element was first postulated by Prof. Leon Chua in 1971.The physical implementation of this device was developed by HP team in 2008.Thereafter memristor as a fundamental circuit element has shown tremendous potential for development of analog and digital circuit. To design circuits with memristors, it is essential to understand the memristor behavior with a simulator.SPICE is a general purpose simulator which is used in the analysis of integrated circuits. This paper will discuss memristor behavior with LTspice simulator which is a popular version of SPICE and implement Memristor model for the analysis of MC(Memristor Capacitor) circuits.

A Unified and Open LTSPICE Memristor Model Library
Electronics, 2021
In this paper, a unified and open linear technology simulation program with integrated circuit emphasis (LTSPICE) memristor library is proposed. It is suitable for the analysis, design, and comparison of the basic memristors and memristor-based circuits. The library could be freely used and expanded with new LTSPICE memristor models. The main existing standard memristor models and several enhanced and modified models based on transition metal oxides such as titanium dioxide, hafnium dioxide, and tantalum oxide are included in the library. LTSPICE is one of the best software for analysis and design of electronic schemes. It is an easy to use, widespread, and free product with very good convergence. Memristors have been under intensive analysis in recent years due to their nano-dimensions, low power consumption, high switching speed, and good compatibility with traditional complementary metal oxide semiconductor (CMOS) technology. In this work, their behavior and potential application...
Memristive Device Fundamentals and Modeling: Applications to Circuits and Systems Simulation
Proceedings of the IEEE, 2000
This paper presents SPICE ready circuit models that system designers can use to accurately measure the behavior of memristor-based large systems. ABSTRACT | The nonvolatile memory property of a memristor enables the realization of new methods for a variety of computational engines ranging from innovative memristive-based neuromorphic circuitry through to advanced memory applications. The nanometer-scale feature of the device creates a new opportunity for realization of innovative circuits that in some cases are not possible or have inefficient realization in the present and established design domain. The nature of the boundary, the complexity of the ionic transport and tunneling mechanism, and the nanoscale feature of the memristor intro-duces challenges in modeling, characterization, and simulation of future circuits and systems. Here, a deeper insight is gained in understanding the device operation, leading to the development of practical models that can be implemented in current computer-aided design (CAD) tools.
The representation of memristor model in MATLAB and Simulink environment. Short paper.
2015
The work describes the various methods of memristor modelling and simulation in the MATLAB and Simulink environment. Previously published papers about memristors and their features are used as the foundation of the work. There are three various methods used in the MATLAB and Simulink for the differential and other equations formulation. The first equation uses the standard system core offer for the Ordinary Differential Equations solutions (ODE) in the m- file form. The second solution is the model construction in Simulink environment. The third method includes a physical modelling using the built-in SimscapeTM system. The results are the basic memristor characteristics and appropriate time courses. The characteristics of all models and their computer simulations are described in the paper.
Journal of Circuits, Systems, and Computers, 2010
Memristor had been¯rst theorized nearly 40 years ago by Prof. Chua, as the fourth fundamental circuit element beside the three existing elements (Resistor, Capacitor and Inductor) but because no one has succeeded in building a memristor, it has long remained a theoretical element. Some months ago, Hewlett-Packard (hp) announced it created a memristor using a TiO 2 =TiO 2ÀX structure. In this paper, the characteristics, structures and relations for the invented hp's memristor are brie°y reviewed and then two general SPICE models for the charge-controlled and°ux-controlled memristors are introduced for the¯rst time. By adjusting the model parameters to the hp's memristor characteristics some circuit properties of the device are studied and then two important memristor applications as the memory cell in a nonvolatile-RAM structure and as the synapse in an arti¯cial neural network are studied. By utilizing the introduced models and designing the appropriate circuits for two most important applications; a nonvolatile memory structure and a programmable logic gate, circuit simulations are done and the results are presented. .

A review on memristor applications
arXiv (Cornell University), 2015
This article presents a review on the main applications of the fourth fundamental circuit element, named "memristor", which had been proposed for the first time by Leon Chua and has recently been developed by a team at HP Laboratories led by Stanley Williams. In particular, after a brief analysis of memristor theory with a description of the first memristor, manufactured at HP Laboratories, we present its main applications in the circuit design and computer technology, together with future developments.
Overview of Memristor based devices and circuits
The fourth fundamental circuit element-Memristor, was mathematically predicted by Prof. Leon Chua in his seminal research paper in IEEE Transaction on Circuit Theory on the symmetric background. After four decade in 2008, researchers at the Hewlett-Packard (HP) laboratories reported the development of a new basic circuit element that completes the missing link between charge and flux linkage, which was postulated by Chua. The new roadmap in the field of circuit designing, soft computing, memory technology and neuromorphic applications are emerged out very quickly in scientific community due to memristor. However the commercial device level memristor is not realized and reported in the literature until now. This paper overviews the some of the pioneer and state of art development in the view of memristor. The criticism constrains about memristor in scientific fraternity are also discussed.
Study of Memristor Models and Its Applications in Logic Circuits
One significant area of nanotechnology is nanoelectronics and a recent development in nanoelectronics is the discovery of the memristor, a fundamental circuit element. A memristor is essentially a nonvolatile nanoscale programmable resistor whose resistance, or memristance to be precise, is changed by applying a voltage across or current through, the device. Memristor has the potential to replace transistors in the digital circuit of upcoming days. Research is in full swing to find the compatibility of this device with existing CMOS technology. Throughout this paper such possible application of the memristor is investigated through SPICE simulation. The initial goal of the paper was to simulate the device characteristics. The secondary goal was to make circuits with the device. Standardization of device model is a big problem in memristor research, which is why a comparison of various models is also presented in this work. The paper has ended with a summary of our work done and possible scopes for future work.

Physical implementation of novel device Memristor and its mathematical model was first demonstrated by HP Labs research team in 2008.Memristor is getting a considerable attention due to its diversified areas of applications from computing to neuromorphic areas.

Chapter 12 Memristor SPICE Modeling
2012
Modeling of memristor devices is essential for memristor based circuit and system design. This chapter presents a review of existing memristor modeling techniques and provides simulations that compare several existing models to published memristor characterization data. A discussion of existing models is presented that explains how the equations of each relate to physical device behaviors. The simulations were completed in LTspice and compare the output of the different models to current–voltage relationships of physical devices. Sinusoidal and triangular pulse inputs were used throughout the simulations to test the capabilities of each model. The chapter is concluded by recommending a more generalized memristor model that can be accurately matched to several different published device characterizations. This generalized model provides the potential for more accurate circuit simulation for a wide range of device structures and voltage inputs. 12.
