This paper proposes a multi-attractor period multi-scroll chaotic system and a second-generation current-controlled current conveyor (CCCII) with a wide tunable range of intrinsic resistance. The newly proposed multi-attractor period multi-scroll chaotic system is constructed by this CCCII. The proposed chaotic system can generate single-attractor period, double-attractor period, three-attractor period, and even more attractor period multi-scroll. The four-dimensional state equation of the chaotic system contains four nonlinear functions for generating multi-attractor period multi-scroll chaos. Since the intrinsic resistance of the CCCII can be adjusted by external voltages or currents, the multi-attractor period multi-scroll chaotic integrated circuit based on the proposed CCCII have a tunable characteristic. It is worth noting that a chaotic integrated circuit has been implemented completely using current signals instead of voltage signals, and more interestingly, it does not contain any passive resistor. The dynamic characteristics of the multi-attractor period multi-scroll chaotic system are given. The circuit designs of the CMOS CCCII and the corresponding chaotic circuit are made in detail. We conduct the numerical and circuit simulations of the proposed chaotic system and the integrated circuit implementation of the chaotic circuit based on the CMOS CCCII. The correctness of the CCCII circuit and the chaotic system are proved through hardware experiments. The comparison between the implementation scheme of the chaotic circuit in this paper and several reported chaotic circuits is conducted.
