Design and realization of grid multi-scroll chaotic circuit based on current conveyers

Abstract

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.
