由于电流反馈运算放大器（CFOA）比传统的运算放大器具有一些显著的优点，因此在混沌蔡氏电路的新实现中，电流反馈运算放大器（CFOA）已被用来代替电压运算放大器（VOA）。在这项研究中，在给出了基于CFOA实现的蔡氏电路的比较研究，我们将提出一种替代的基于CFOA实现的蔡氏电路结合CFOA为基础的电路拓扑结构提出的非线性电阻和电感元件在文献中。这种实现为研究蔡氏电路和高频混沌振荡的读者提供了一种替代方案。在时域和频域进行的PSpice仿真实验证实，该电路可以产生蔡氏电路的原始混沌振荡，它具有优良的性能在高频。
Because they offer some significant advantages over conventional operational amplifiers, current feedback operational amplifiers (CFOAs) have been used instead of voltage operational amplifiers (VOAs) in new implementations of the chaotic Chua’s circuit. In this study, after giving a comparative investigation of CFOA-based realizations of Chua’s circuit, we will present an alternative CFOA-based realization of Chua’s circuit combining the CFOA-based circuit topologies proposed for nonlinear resistor and inductor elements in the literature. This realization offers an alternative solution for readers studying Chua’s circuit and high-frequency chaotic oscillations. The PSpice simulation experiments performed in both the time and frequency domains confirm that the proposed circuit can generate the original chaotic oscillations of Chua’s circuit and that it exhibits excellent performance at high frequencies.
