Summary:
We propose a forced chaos generator with a CMOS variable active inductor circuit. The equivalent inductance of the variable active inductor in the proposed circuit can be controlled by an external voltage. The oscillation frequency of the circuit can be tuned by applying an external signal. We then realize the folding-and-stretching mechanism of chaotic motion by applying a periodic external signal. The chaotic dynamics are confirmed through SPICE simulations with TSMC 0.35 μm CMOS semiconductor process parameters. Moreover, we present bifurcation phenomena, which are generated when the amplitude and the period of the external signal are changed as bifurcation parameters.
