Hi again everyone...I am really bad at this type of analysis. In particular, I have an issue forming equations (using KCL) from the small signal model.
The question and the small signal model is attached.
I want to form a KCL so I would have
\( I_i = I_o\) from my drawing. From the solution provided to me, I know that I am already wrong.
The solution I am trying to get to is:
\(\frac{v_o  A_0_l v_d}{R_o} + \frac{v_0 v_i}{Ri} = 0 \)
and \( v_d = v_i  v_o\)
I may have 'i' wrong with 'I' subscript because it is not clear on the solution. This is the formula would like help with if possible. Thank you!
