The chaotic characteristics of the circuit can be verified by the dynamic analysis, numerical simulations and circuit experiments. Furthermore, in order to control the proposed chaotic circuit, a new type of analog time-delay feedback control circuit is designed. The controller is used to realize the time delay in the state variables of the chaotic circuit, and feedback the resultant state variables to the original circuit. The results from the numerical simulation and the circuit experiment show that the proposed time-delay feedback controller can realize the stabilization control for the chaotic circuit. Finally, the bifurcation behavior of the circuit under the time-delay control is studied; results show th
