Research of a Period Doubling Bifurcation of Chua´s Circuit

According to nonlinear characteristic of Chua´s circuit, phase diagram and Poincare cross section are used for the circuit analysis, a period doubling bifurcation of Chua´s circuit is researched when a capacitance parameter is change in a certain range, the attractor of annulus is researched which is displayed by the circuit. We can glimpse at that there are extraordinary abundant chaotic characteristic with Chua´s circuit. Because of the representative of Chua´s circuit in configuration, the research methods of chaotic characteristic of the circuit are provided with definite universal ability
