Hi all,
I am new on here and seeking some help please.
I am struggling to answer the following revision question.
An RC coupled amplifier has a feedback network added to modify its performance. Before the addition of the network, the amplifiers gain was 25<180(degrees).
3% of the output voltage is fed back to the input via the feedback network, which introduces a phase shift of 60(degrees) at the midband frequency of the amplifier. Determine the following:
1) the value of the feedback factor in polar form
2) the loop gain, in polar form
3) the closed loop gain in polar form
4) the gain and phase margins of the feedback amplifier.
Thanks in advance
