摘要/Abstract

摘要：采用电流反馈放大器(CFOA)设计了一个由3个积分电路、2个非线性电路和1个减法电路组成的混沌电路,该电路能产生网格多涡卷混沌吸引子.CFOA具有很好的频率特性和端口特性,使得该电路结构简单、中心频率高、有源器件少.电路仿真结果与数值仿真结果一致,仿真结果表明电路设计正确.

关键词： 网格多涡卷混沌吸引子, 电流反馈放大器, 电路实现

Abstract: A chaotic circuit is designed using current feedback operational amplifiers (CFOAs).The circuit consists of three integrators,two nonlinear circuits,and one subtractor.The circuit can generate grid multi-scroll chaotic attractors.The central frequency of the circuit is higher with fewer active components and simpler circuit construction for the good frequency characteristic and port characteristic of the CFOA.The circuit simulation results are in agreement with the numeral simulation results.Simulation results show that the designed circuit is correct.

Key words: grid multi-scroll chaotic attractors, current feedback operational amplifier, circuit implementation
