A New Circuit Design for Chaotic Oscillator

Since the conventional Duffing circuit is limited to low frequency signals detection, this paper proposes a new type of Duffing circuit for high frequency signals, which effectively avoids the instantaneous saturation problem. It also gives an operational block diagram and the detailed design of the main unit circuit. By adjusting the parameters of several elements, the circuit can realize the wide frequency detection from low to high frequency. Simulation results prove that the circuit is a chaotic system and has the extreme sensitivity to the initial condition.
