提出了一种仅用电流反馈放大器实现网格多涡卷混沌系统的方法. 首先用电流反馈放大器设计非线性函数电路；再用电流反馈放大器设计网格多涡卷混沌电路，根据混沌吸引子参数确定电路参数，由于电流反馈放大器具有较好的频率特性和端口特性，使该电路的工作频率高、电路结构简单、使用元件少；最后，通过电路仿真验证该方法的可行性.

In this paper, a method is proposed to realize the grid multi-scroll chaotic system with the current feedback operational amplifier (CFOA). Firstly, nonlinear circuit is designed based on the CFOA. Then the grid multi-scroll chaotic circuit is designed and relevant circuit parameters are calculated. Finally circuit simulation is conducted, and the results show that the circuit has a higher central frequency, needs less components, and possesses simpler circuit structure, good frequency characteristic and port characteristic of the CFOA.-
