Difference RC phase shift oscillator & Wein bridge oscillator

RC phase shift oscillator

Wein bridge oscillator

This oscillator is used for low frequency range. This oscillator is used for low frequency range since both are RC oscillator.
Feedback network provide 180° phase shift. Feedback network do not provide 180° phase shift.
Op-amp is used in inverting mode. Op-amp is used in non-inverting mode.
Op-amp introduces 180° phase shift. Op-amp does not introduce 180° phase shift.
Amplifier gain |A| >=29 Amplifier gain |A| >= 3
3RC section in feedback. Low frequency range since both is RC oscillator.
Difficult to adjust frequency variation. Easy adjustment of frequency by varying both capacitors.
