Problem 2: BJT Small-Signal Voltage Amplifiers in the lectures, we covered in detail the analysis of an npn BJT amplifier that utilizes a single-supply DC biasing. In this problem, you will meet two additional amplifier architectures- one that is based on dual DC supplies combined with a DC current source, and the other that utilizes a pnp BJT with single-supply biasing. In both problems (below) you need to manually find the amplifier's Q-point (that is, the DC values of Ic...
