运算放大器混沌

A Operational Amplifier Chaos

设计了一种具有混沌动力学特性的三阶自治电路。电路中的非线性或分段线性器件无须特意构造并具有准确的数学表示式。电路完全由模拟运算单元组成，结构清晰。方程中的全部变量及其导数皆以电路中的对地电压表示， 便于实验观测。对该电路混沌的特性进行了模拟计算研究和实验观测， 模拟运算结果与实验结果相符。

ln this paper we design a third-order autonomous circuit with chaotic dynamics.Thenon-linear or piecewise linear unit in the circuit is not constructed specially and it has accurate mathenatical expression.The circui is composed of the analogue operational units completely and its structure is clear.All variables and their derivatives in the equation are indicated as ground voltages in the circuit.It is easy for experimental observation.The numerical simulation and experimental observation about chaotic specificity of the circuit have been done and the results agree.
