The wein bridge's amplitude is stable across a very broad spectrum of frequencies, because of the NTC light bulb in the feedback path.what is the difference between RC phase shift oscillator and a wein bridge oscillator?
They're very good, I have done a few of them ...Bill Hewlett (of HP) made HP by making the first really stable, really pure sine wave generator, whose design you see a simplification of above. The light bulb used as a automatic gain control was a major breakthrough.
