I need to be able to design a BJT amplifier with certain specification:

Open circuit(no load) voltage gain: 50(±10%)
Type of transistors: BJT
Number of transistors: no more than 3
Power supply: 15V relative to the ground
Output resistance: no larger than 15k

Input resistance: no less than 200k

Quiescent current drawn from the power supply: no larger than 2mA
Max no-load output signal swing: no less than 8V peak to peak

How would i go about doing this? Can you show your work as well?

Why? So that you don't have to do it and can turn in someone else's work as your own?

That's not how it works -- and if it did it wouldn't help you out as much as you might think.

You need to show YOUR best attempt to do YOUR homework. Don't worry about it being right or complete. Make the best start you can. Then we can give you feedback on where you are going well and where you are going astray and help get you back on track.

Sorry about that. I have a very rough draft of my work attached. I don't know if my thought process is correct or not. I feel like I have to change my design because in order to get a large gain and input resistance, I would have to use a CE amp and as for a small output resistance, I would have to use a CC amp. I still yet have to simulate the circuit. Another thing that I wanted to know is how do I calculate the capacitor values? I only have a wide range of capacitors available to me (specifically 0.022uF, 0.01uF, 0.1uF, 1.0uF, 100uF and 10uF).
