Problem 2 (10 points) In the amplifier shown in Fig. 2(a), assume Fig. 2(b) that I4 is ideal. Do not ignore the ro of the transistors for this problem, but you can assume that Ri is much smaller than any transistor o I1 and I2 ideal current sources. Also, assume in are (a) Find the small signal differential gain out/vdm of the Fig. 2(a) amplifier in terms of the appropriate small-signal parameters. Then express your answer in terms of appropriate...
k) Biasing of a BJT transistor is the setting of the collector emitter voltage and the collector current to the desired dc values. These voltages and currents determine the operating point (quiescent point, Q point).

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...
