Exploring resistive switching‐based memristors in the charge–flux domain: A modeling approach

Abstract

SUMMARYWe analyzed resistive switching-based memristors by using the charge-flux relations instead of the traditional current-voltage approach. We employed simulated and experimental data to develop a model that can be easily included in circuit simulators. Physical simulations of devices with different conductive filament sizes were employed to fit the 3-parameter model introduced. Later on, the relations between the model parameters and the conductive filament geometrical features were characterized in-depth. In addition, a model to obtain the energy employed in the reset process was presented. Finally, we used the model to estimate the experimental conductive filament radius distribution using a set of 3000 reset cycles.

Fuzzy adaptive singular value decomposition cubature Kalman filtering algorithm for lithium‐ion battery state‐of‐charge estimation

“…Common lithium-ion battery equivalent models include Thevenin equivalent model, PNGV model, and second-order RC model. [33][34][35][36][37][38] Taking into account the requirements of battery simulation accuracy and the principle of minimizing the amount of calculation, a secondorder RC equivalent model is selected to perform equivalent simulations of lithium-ion batteries. For the internal resistance of the battery that is different during charging and discharging, the internal resistance of the battery for charging and discharging is calculated separately to form a double internal resistance second-order RC model.…”

Polymer/TiO2 Nanorod Nanocomposite Optical Memristor Device

“…In order to further analyze the results obtained for these test memristor devices, we have studied an approach proposed by Picos et al in the literature. , In this case, the basic model of the memristive device has been derived using a framework in which memristors are described by charge and flux instead of current and voltage. − The charge Q is defined as the first momentum of the current, and the flux ϕ is defined accordingly for the voltage as follows and …”
