(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Derive an expression for the equivalent small-signal conductanceG(or resistance_{eq}R)._{eq}

2. Relevant equations

G= [itex]\frac{i_t}{v_t}[/itex]_{eq}

v_{t}= v_{g}

v_{s}= 0

v_{d}= -v_{t}

3. The attempt at a solution

Attachment - EE HW 2

I drew the small-signal circuit, from what I gather it seems to be correct although I am a bit rusty on that. I began by using KCL at node v_{g}and solving forGbut I'm really unsure as to whether I've started this right. Looking at my work so far, to me, it seems to be on track for solving for_{eq}G. If someone could just simply check my work/small-signal model over from what I have so far it would be greatly appreciated to earn some confidence on continuing my work! Thank you._{eq}
