混沌振荡器的计算机仿真

Computer simulation of chaotic oscillator

提出了用频变负电阻(FDNR)实现混沌振荡器的新电路,该电路结构简单,易于集成,仅用一个接地的频变负电阻作为有源器件,用二极管提供必要的非线性。并给出了电路的数学模拟和PSpice仿真。模拟和仿真结果表明,二者取得了很好的一致。

In this paper, a chaotic oscillator circuit using a frequency dependent negative resistor (FDNR) is proposed. The circuit relies on a grounded FDNR as the active element and employs a general purpose signal diode to provide the necessary non-linearity. PSpice simulation and numerical simulation are given to confirm the design.
