The phase shift oscillator shown in the figure is a phase shift oscillator, which is a type of RC feedback circuit oscillator. There are three RC circuits
in the feedback loop , each
with a maximum phase shift close to 90. . The oscillation occurs at a frequency such that the total phase shift through the three RC circuits is 1800. The amplifier is an inverting amplifier,
which itself provides a phase shift of 1800, making the total phase shift of the oscillator 3600 (Oo) to meet the requirements of the oscillation conditions.
