A novel approach to Chua’s circuit based on current conveyers is proposed which overcomes the difficulties of the signal frequency being too low and the current waves and the corresponding phase diagrams not easy to test for this kind of circuit. Active simulated inductor and piece-wise nonlinear resistor in the circuit are all realized by current conveyers, so that the circuit is more stable and can work in higher frequency than does the usual Chua’s circuit. The circuit also has the advantages in that the current waves and the corresponding phase diagrams can be tested easily. The circuit has been designed, simulated, realized in hardware and tested. The experimental results are in good agreement with simulation results,which confirms the validity of the design. The circuit is suitable for secure communications.
