摘要
研究了一种基于电流放大器的电流型混沌振荡器。该振荡器工作在高频上，适用于片上实现。用偏置电压控制其混沌行为。各种检测混沌的方法，如李雅普诺夫指数，李雅普诺夫维数，频谱和相位肖像被使用，以确认电路的混沌行为。采用典型的0.35 μ m CMOS技术，仿真结果与理论结果完全吻合。
An Integratable Chaotic Oscillator with Current Amplifiers
A current-mode chaotic oscillator based on current amplifiers is studied. The oscillator operates on high frequencies and is suitable for on chip implementation. Its chaotic behavior is controlled by means of a bias voltage. Various methods for detecting chaos, such as the Lyapunov exponents, the Lyapunov dimension, the spectrum and the phase portraits are used, in order to confirm the chaotic behavior of the circuit. Simulation results, using a typical 0.35 mum CMOS technology, fully coincide with theoretical results.
