2. Figure 2 (a) shows a BJT cascode amplifier with a cascode active load. Figure 2 (b) is the corresponding small signal equivalent circuit for Q1 and Q2 in Figure 2 (a). The transistor parameters are ß = 120 and Vi = 80 V. Assume 9m >>V, = 0.026 V. The Vpe voltage is such that all transistors are biased in the active region.
