摘　　要：提出了一种利用同相电流传输器(CCⅡ+)实现网格多涡卷混沌吸引子的方法.首先,构建一个三维网格多涡卷混沌系统,并对该系统进行基本动力学特性分析.其次,在考虑电流传输器端口寄生参数的情况下,构建了电流输出的饱和函数电路并设计一个具有串联结构的网格多涡卷混沌电路,使得该电路的工作频率得到提高.最后,通过硬件电路实验验证了该方法的可行性.In this paper, we propose method of generating grid multi-scroll chaotic attractors with the positive-type second generation current conveyors （CCII＋）. Firstly, a three-dimensional grid multi-scroll chaotic system is presented. Some basic dynamical properties are studied. Furthermore, we construct the saturation functions with current output and design the chaotic system with series structure by using current conveyers. In the whole design the port parasitic parameters of current conveyers are taken into considerations. By analyzing we could learn that the circuit can work in a higher frequency range. Finally, the effectiveness of this method is verified by circuit implementation.
