摘要:

采用逐段线性电路理论，对混沌产生的原理和方法进行了研究．利用集成运算放大器，设计了产生混沌的电路，进而实现混沌现象，并用仿真软件对电路进行仿真验证．结果表明，采用此种方法，可以较好地找出混沌与各种电路元件参数之间的关系和规律，这对进一步研究设计专用混沌集成电路及混沌在保密通信中应用有积极意义．

Abstract:

The circuit principle and the method of engendering the chaos are studied with piecewise linear circuit theory. The circuit producing chaos with integrated operation amplifier is designed and the chaos phenomenon is realized. The circuit is proved by using the emulation software.The result shows that the relationship between the chaos and circuit element parameters can be discovered easily with this method and this method is of positive significance in studying and designing the special integrated operation amplifier of chaos and in security communication.
