摘要
提出了一种电流型变参数的蔡氏电路．首先用ＯＴＡ（电流型跨导运算放大器）实现了仿真接地电感和分段线性电阻的综合．之后，用ＯＴＡ综合了电流型变参数蔡氏电路，并计算了该电路的Ｌｙａｐｕｎｏｖ指数，做出了功率谱及Ｐｏｉｎｃａｒｅ截面图．最后，通过实验探讨了系统进入混沌的道路．
In the paper,a new variable parameter of current type Chua’s circuit is proposed.Firstly,grounded inductor and piecewise linear resistor are synthesized with OTA(Operational Transconductance Amplifier).Then,a new variable parameter of current type Chua’s circuit is synthesized with OTA.The Lyapunov exponents are calculated;the power spectrum and the Poincare section are given. Finally,the road to chaos is discussed by experiments.
