The first stage is a common-emitter amplifier and the


You are required to design a two-stage amplifier employing what you have
learned so far in this course. The first stage is a common-emitter amplifier and the second stage is a common-collector stage. You should use one npn (2N3904) and one pnp transistor (2N3906) to design the circuit to meet the design criteria. Use the transistor datasheets to find out the parameters you need for this lab.

The deign requirements for the whole amplifier are:
Voltage Gain: 40 < | AV | <50
Input Resistance: Rin > 25k-ohm
Output Resistance: Rout < 50-ohm
Total Power Consumption: Pdiss < 25mW
Output Voltage Swing: | Vout | > 3V
