(b) For the circuit shown in Figure 4b, the transistor is biased with a constant source lo=1 mA. The transistor parameters are B = 100, VBe(on) = 0.7 V, Vr = 26 mV and the Early voltage VA= 00. Assume that all capacitors have negligible reactance at signal frequency. (1) Find the de voltages at the base, emitter, and collector.
