What is the phase shift of a circuit?
The phase shift network in this circuit, consists of three RC sections. At the resonant frequency f o, the phase shift in each RC section is 60 o so that the total phase shift produced by RC network is 180 o.
How does feedback work in a FET oscillator?
In a FET phase-shift oscillator voltage series feedback [that is, feedback voltage proportional to the output voltage V out and supplied in series with the input signal at the gate is used. The frequency of the oscillator output depends upon the values of capacitors C and resistors R used in the phase shift network.
