用电流反馈运算放大器改进典型蔡氏合成电感电路的实现
Improved realization of canonical Chua's circuit with synthetic inductor using current feedback operational amplifiers
摘要：
本文提出了一种改进的无电感三阶正则蔡氏电路的实现方法。该电路采用电流反馈运算放大器（CFOA）设计有源元件和合成电感。采用CFOA的原因是它们具有更好的特性，例如高转换速率、高操作速度等，当与使用电压运算放大器设计的电路相比时，这使得电路能够在更高的频率范围内工作。除此之外，CFOA的包含提供了直接表示系统的状态变量的缓冲输出。在时域和频域的Multisim仿真证实了所提出的电路在高频下的性能的理论估计。通过硬件实验也证实了这一点。
英文摘要：
In this paper, we report an improved implementation of an inductorless third order autonomous canonical Chua's circuit. The active elements as well as the synthetic inductor employed in this circuit are designed using current feedback operational amplifiers (CFOAs). The reason for employing CFOAs is that they have better features such as high slew rate, high speed of operation, etc., which enable the circuit to operate at higher frequency ranges, when compared to the circuits designed using voltage operational amplifiers. In addition to this, the inclusion of CFOAs provide a buffered output which directly represent a state variable of the system. The Multisim simulations in the time and frequency domains confirm the theoretical estimates of the performance of the proposed circuit at high frequencies. It is also confirmed through hardware experiments.
