Figure Ql shows a feedback amplifier without details of the bias circuit. (a) Find the feedback topology and sketch the feedback block. (b) Show that if cA is large then the elosed loop voltage gain is given approximately by Af=VdNt=(RF+RE)RE (c) If RE is equal to 50, find RF that will result in a closed-loop gain of approximately 25V/N. (d) Calculate the insut and output resistances of the closed-loop amplifier
