1. The problem statement, all variables and given/known data Find the differential gain int terms of small signal parameters of the attached image. 2. Relevant equations I don't think we need any equations. Just some basic mosfet knowledge. Not going to draw the small signal circuit, because it would take a long time. 3. The attempt at a solution My attempt at the question is attached along with the schematic. When comparing my answer to the answer in the solutions, I am missing a factor of (1+gm(ro6 || ro7))^-1 Where || means "in parallel." I am really close but it looks like I am missing a critical part. Thank you for your help.
