Chaotic Circuit Research Based On The Current Conveyor

To start research work this paper focus on Chua's circuit, current conveyor. The definition of chaos, and chaos of the important concepts in several aspects of the main features of which were outlined on the chaos theory.Then the application prospects and the development trend of Chaotic Circuit were detailed introduced.Then the development and port characteristics of current conveyor were outlined. Single-scroll chaotic oscillator circuit design approach based on current conveyor was researched.Single-scroll chaotic oscillator circuit design method is simple,flexible,diverse. Frequency of chaotic signal generated by the cicuit is high and suitable for high Frequency communication.It also detailed the circular mapping theory.Chaos in chaotic oscillator circuit by using circular mapping was researched.Multi-scroll chaotic attractors based on Chua's circuit have also studied.Dual-scroll chaotic oscillator circuit based on Chua's circuit was designed,Chaotic circuits control can be realized by changing the current. Multi-scroll chaotic circuit based on AD844 was designed. To achieve the general formula of the parameters of nonlinear resistive circuits by using piecewise linear function was given, so that the generation of chaos is not a blind. In this paper,Chaotic circuit generated 3-5 scroll chaotic attractors was gived,the designed circuit was simulated with the Pspice simulation software to verify the correctness of the circuit.Then compared the performance of several simulation inductor composed of impedance The converter.inductor in chua's circuit was replaced by idear simulation inductor ,the circuit was simulated with simulation software to verify the superiority of simulation inductor.The chaotic circuits composed of simulation inductor was easy to implement. The circuit was easy to start-up.The frequency of multi-scroll chaotic oscillator baed on current conveyor was improved,to solve the problem of low frequency of Chua's circuit.The circuit can be used in chaotic secure communication.Finaly,problem encountered in the design of chaotic oscillator are summarized,and the development of chaotic circuit are discussed.
