We propose a novel RC sinusoidal oscillator architecture suitable for very low frequency generation. The oscillator is also attractive in the sense that the lower the oscillation frequency, the lower the necessary gain required to start oscillations. Further, the proposed architecture is active-circuit-independent and can be realized in any suitable way.(More)
We first present a simple circuit design method for obtaining a non-autonomous chaotic oscillator circuit from any given second-order sinusoidal oscillator with two capacitors. The proposed method relies on applying a periodic pulse train as the excitation source and an addition of signum-type nonlinear self-feedback to the given sinusoidal oscillator. The(More)
