Obtain the curve trace for a "Darlington Pair" of Bipolar Junction Transistors. A Darlington Pair consists of two transistors with the first BJT driving the base terminal of the second transistor as shown in Figure 1 below. A. Set up the primary sweep voltages for V1 the same as shown in the lecture notes (see the Darlington pair IV curve). B.
