Abstract:
An oscillator circuit includes a Wien-bridge oscillator. A non-detuned oscillating signal and a detuned oscillating signal are tapped from the Wien-bridge oscillator. A sum of a weighted detuned signal and a weighted non-detuned signal is coupled as feedback signal to the Wien-bridge to control the oscillation amplitude.
