摘　　要：以普通运算放大器作为有源器件,设计了饱和函数序列电路,给出了电路频率临界值.将饱和函数序列电路应用于多涡卷混沌电路设计,研究了饱和函数序列幅度、宽度、斜率等参数对多涡卷混沌吸引子相图的影响.设计了基于参数可调的饱和函数序列的混沌电路,研究表明,通过选择合适的参数,可以调控多涡卷吸引子大小和形状.设计的饱和函数序列电路稳定且灵活,有利于其在多涡卷混沌电路中的应用.Taken the operational amplifier as the active devices, the saturated nonlinear function series circuit is designed, and the critical circuit frequency is determined. The saturated nonlinear function series circuit is applied into the multi scroll chaotic circuit, and the influence of the amplitude, width, slope of the saturated nonlinear function series on multi scroll chaotic attractor is also investigated. Moreover, a parameter adjustable chaotic circuit is designed based on the saturated nonlinear function series. The results show that the size and shape of the multi scroll attractors can be adjusted by changing parameters. The designed saturated nonlinear function series circuit is stable and flexible, and it is propitious to the application of multi scroll chaotic circuit.
