In this paper, the dynamics analysis of four-order Chua' s circuit was investigated through the Lyapunov exponent, bifurcation and power spectrum, which developed the corresponding domain for chaotic motion and periodic motion. Furthermore, the four-order Chua' s circuit was designed through the Multisim circuit simulation software, and then the single or two-scroll chaotic attractors were given. The results are presented to demonstrate the effectiveness of the proposed method.
