In a phase shift oscillator, the frequency of oscillation and the required amplifier gain are determined using frequency domain analysis. The circuit typically consists of an amplifier and a phase-shifting network. The phase-shifting network usually includes three RC stages, each providing a phase shift of 60° to achieve a total phase shift of 180°, which, when combined with the 180° phase shift introduced by the amplifier, _____ _____ ___ __________ _____ _________ _________.
