Hello all. I've been working on this question and it's killing me. I have solved the entire question (there are more parts ), but I could only do it once I was told that \(\small V_{GS} = - V_S + V_G = - V_S\).
I was just wondering why \(\small V_{G}\) is at 0. I am having a hard time getting my head around that.
Shouldn't \(\small V_{G}\) simply be \(\small V_{i}\)?
\(dI = \frac{\partial I}{\partial V_{GS}} dV_{GS} + \frac{\partial I}{\partial V_{DS}}dV_{DS}\)
