Image courtesy : Internet RC phase shift oscillators are commonly used for generating audio frequencies, that is 1Hz to 10MHz. RC phase shift oscillator consist of an inverting amplifier followed by a feed back network with phase shift of 180 degree. The 180 degree phase shift at the feedback can be obtained by the combination …
