| Description | We now study the effects of feedback on amplifier impedance and gain and obtain some useful relations among the return difference, the null return difference, and impedance functions in general.Refer to the general feedback configuration of Fig. 29.6. Letwbe a transfer function. As before, to emphasize the importance of the feedback elementx, we writew=w(x). To be definite, letw(x) for the time being be the current gain between the output and input ports. Then, from (29.24) we obtain(30.1)yielding(30.2)provided thatw(0)≠0. This gives a very useful formula for computing the current gain:(30.3)Equation (30.3) remains valid ifw(x) represents the transfer impedancez=V/Iinstead of the current gain.
