摘要

提出了一种基于粗立方型CMOS电阻的蔡氏混沌振荡器的实现方法。一个简单的电流镜和一个单端差分对构成一个接地的非线性CMOS电阻。这种非线性类似于粗糙版的立方电压电流特性。模拟了单涡旋和双涡旋混沌吸引子的运动轨迹。

A Chua’s chaotic oscillator based on a coarsely cubic-like CMOS Resistor

An implementation of a Chua's chaotic oscillator is proposed based on a coarsely cubic-like CMOS resistor. A simple current mirror and a single-ended differential pair form a grounded nonlinear CMOS resistor. Such nonlinearity resembles a coarse version of cubic-like voltage-current characteristics. Simulated trajectories of the single-scroll and the double-scroll chaotic attractors are demonstrated.
