Exercise 9

Dear Prof. Enz, dear TAs,

I have some questions about exercise 9:

1) For exercise 9, problem 1.2, I don't understand how to find eq. 8b and 8c. May I, please, have some hints about it?

2) For exercise 9, problem 1.2, I don't understand why in eq. 8a, we get A_v R_s, why do we get to multiply by the gain?

3) For exercise 9, problem 1.2, is it, please, possible to get the reference in the lesson to the formula eq. 12?

Thank you,

Alexandre

Hi again,

1) This is similar to the mock-up exam, I hope you get the hint about it. The different thing is that this exercise calculate the output voltage noise.
2) 4kTR_S is the input voltage noise, it becomes Av^2 4kT R_S at the output. You can find it in (9).
3) check Ch.6 slide 10

Best,
Hung-Chi
