What is the formula of the phase angle when working with a feedback amplifier with a certain transfer function A(jw)?
Homework Answers
Usually to find phase angle for Af(jw)=tan-1( imaginary part of Af(jw)/ real part of A(jw))
But here for oscillators or where opamp is used them usually phase shift will be integrals multiples of 90.
For inverted opamp= 180 will be there
For oscillators = 270 will be there.

inverting amplifier
An inverting amplifier uses an op-amp whose frequency response is A(s) =ωu/s .Determine the transfer function of the closed loop circuit and compute thebandwidth. Re-work the bandwidth when the op-amp has a different model, i.e.,A(s) = A/(1+s/wp).Compare the two answers. Where is s=jw.
