Behavioral Simulation Modeling Of Single Photon Avalanche Diode, Xu Yue, Xiaopeng Xie, Yue Heng
Journal of System Simulation
Abstract: An accurate behavioral simulation model for single photon avalanche photodiode (SPAD) was proposed. This presented model solved the convergence problem existed in SPAD avalanche current simulation, and achieved the basic static DC and dynamic AC behaviors modeling. The model functions were extended. Two important statistical effects of dark-counting and after-pulsing phenomena were included in this model according to their physical mechanisms. The model has been written in Verilog-A hardware description language, showing good characteristics of transplantation and universality. A good agreement with more than 90% accuracy is achieved between the model basic simulations and the experimental results, proving the …

Novel Modeling Of Memristive Cellular Neural Network And Its Circuit Simulation, Xiaohong Zhang, Linyu Liao, Lianghua Yu
Journal of System Simulation
Abstract: The memristor as the fourth fundamental circuit component included along with the resistor, capacitor and inductor could simulate the storage memory function of brain neural network. A traditional three-dimensional CNN was designed, and the output function was implemented with the nonlinear characteristics of a flux-controlled memristor. The conventional electronic devices in Multisim were utilized to simulate flux-controlled memristor which simplified the output function part of the circuits. To compare with the CNN system which has chaotic behaviors, the circuits of novel memristive cellular neural network not only can show a chaos attractors phenomenon, but also the inner magnetic energy …

Design And Simulation Of Heterogeneous Magnetron Memristive Chua Circuit, Xiaohong Zhang, Lijuan Wan, Keliu Long
Journal of System Simulation
Abstract: A nonlinear circuit containing two heterogeneous magnetron memristors which based on the three-order classic Chua circuit is designed, its dimensionless fifth-order mathematical model is proposed. Due to the difference in the design of the characteristic equation of the two magnetron memristors, their positions form a symmetrical structure with respect to the capacitor. The existence of chaotic properties is proved by analyzing the stability of the system equilibrium point and Lyapunov exponents. The model of five-order heterogeneous memristive Chua system and two heterogeneous magnetron memristors are implemented by Multisim. Numerical calculation and experimental results show that heterogeneous magnetron memristive Chua …

Simple Chaotic Circuit Based On Memristance Function With Real Exponents Power, Xiaohong Zhang, Yanli Qi
Journal of System Simulation
Abstract: The simplest chaotic circuit contains only three circuit elements: a linear passive inductor, a linear passive capacitor and a nonlinear active memristor. In the design of memristors, power of memristance function polynomial with integral exponents is commonly used. On this basis, a general memristor is designed, of which the memristance function polynomial uses power with real exponents, a simple chaotic system is constructed based on the designed memristor. The influence of integral exponents, real exponents and linear parameters on dynamic behaviors is investigated, and chaotic behaviors are analyzed qualitatively using Lyapunov exponents. The Matlab and Multisim simulation results show …

Fractional Control And Generalized Synchronization For A Nonlinear Electromechanical Chaotic System And Its Circuit Simulation With Multisim, Zhen Wang, Tengfei Lei, Xiaojian Xi, Wei Sun
Turkish Journal of Electrical Engineering and Computer Sciences
Two fractional differential controllers, described and validated by using the fractional order stability theorem and the Gershgorin circle theorem for a self-sustained electromechanical system consisting of a van der Pol-Duffing coupled oscillator, were studied in this paper. Based on the idea of a nonlinear observer, a new method for generalized synchronization (GS) of this system is proposed. Finally, the circuit simulation results demonstrate the correctness and the effectiveness of the proposed control and GS strategy.

All Computer Science and Engineering Research
This paper presents a unified approach to mixed-mode simulation. It investigates the algorithms for both logic and circuit simulation, considering their similarities and differences, and a general framework is presented for integrating the two algorithms in uniform manner. The time advance mechanisms and component functional evaluations of the algorithms are show to be similar in nature, and mechanisms for the translation of information represented uniquely in the two algorithms are given. The resulting integrated algorithms is capable of performing mixed-mode simulation, where a circuit is partitioned into discrete and continuous regions, and each region is simulated at the appropriate level. …
