Amplitude control in a twin-T bridgeRC-oscillator using a window comparator
Igor M. Filanovsky, Keith A. Stromsmoe · International Journal of Electronics · 1986
The paper describes amplitude control which is achieved by restoring, during each oscillation period, the voltage at the capacitor connected between the inner node and ground of the twin-T bridge RC-oscillator. The calculations of the amplitude transient, steady-state waveforms and total harmonic distortion are given. All calculations were experimentally verified.
