Abstract

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. Numerical simulations of a derived nonlinear model as well as experimental results are shown.
