B/Considering the three types of Power Amplifier Circuits (Class A, Class B, and Class C): 1. Where is the Q point located (biasing quiescent point) in each type before applying an AC signal? 2. Among these three types, which one can provide linear amplification, and which one cannot? 3. Compare their efficiency.

a) Assume that i) both the coupling capacitors and the emitter capacitance are large enough to have zero impedance (i.e. short circuits), ii) the frequency of input signal is low enough to ignore transistor internal capacitances. Consider the common emitter (CE) amplifier shown in Figure Q1.a. 1) Draw the low-frequency small signal equivalent circuit considering the above assumptions. 2) Show that the maximum voltage gain is Ay(max) = –40lcRc if ro « Ta, (R1//R2) » r7, Tq » Rs, R, » Rc. o+V ce R C.
