Abstract

This research paper reports a novel design for third order chaotic and hyperchaotic oscillator with cubic nonlinearity using single operational trans-resistance amplifier (OTRA) and few passive elements. The key nonlinear dynamical characteristics in terms of sensitivity, divergence, equilibrium point and Lyapunov exponent are recorded in this literature. The operational activity of the proposed oscillator based on OTRA is integrated using 0.25 µm TSMC CMOS parameter. For the generation of hyperchaotic oscillator, an external capacitor is added to the third order chaotic oscillator. To justify the theoretical nonlinear dynamics of proposed chaotic oscillator, PSPICE simulation by using CMOS based OTRA and experimental investigation using IC AD844 based OTRA are well implemented.

使用OTRA的自主混沌和超混沌振荡器

摘要

该研究论文报告了一种新颖的设计，它使用单运算跨阻放大器（OTRA）和少量无源元件，具有三次非线性的三次非线性混沌和超混沌振荡器。在文献中记录了关键的非线性动力学特性，包括灵敏度，发散度，平衡点和李雅普诺夫指数。所建议的基于OTRA的振荡器的工作活动是使用0.25 µm TSMC CMOS参数集成的。为了生成超混沌振荡器，在三阶混沌振荡器上增加了一个外部电容器。为了证明所提出的混沌振荡器的理论非线性动力学合理性，使用基于CMOS的OTRA进行PSPICE仿真以及使用基于IC AD844的OTRA进行的实验研究得到了很好的实现。
