Generation and implementation of grid multiscroll hyperchaotic attractors using CCII+

The grid multiscroll hyperchaotic attractors generated by positive-type second-generation current conveyor (CCII+) are investigated. A fourth-order grid multiscroll hyperchaotic system is presented by introducing two nonlinear functions into hyperchaotic system. Then the system is designed and physically implemented using CCII+. The values of the circuit elements are obtained systematically based in the saturation of the CCII+ to create current staircase function series. The experiment results are verified that the proposed simple oscillator can generate grid multi-scroll hyperchaotic attractors with higher frequency.
