1 M Voc R Rc R th VRBRE LO Q1 Q2 R, Consider the circuit shown above. R = 20k12, R. = 60k12, R, = 2K12, R, = 50082, R = 5k12, and R, = 3k 2. The DC supplies have not been specified. However, you are given that Is = 2 mA, 1s = 1 mA, and both BJTs are in the forward active mode. B= 99. For Q1, V, is infinite. For Q2, V = 50V. (a) Draw the small signal equivalent for the entire circuit. You may use either the n- or T- model for each device. (b) Determine the gain of the circuit. You may do this by analyzing the circuit you drew in part (a) or any other valid method. (c) Determine the output resistance looking into the collector of Q2. You may do this by analyzing the circuit you drew in part (a) or any other valid method.
