Starting the last problem on my EE summer homework assignment for the Fall semester, I wanted to post my thoughts on how to find the resistances before I went ahead and did all the work. I am given what seems to be a fairly simple circuit and asked to find two resistances. 1. The problem statement, all variables and given/known data (Attachment 1 - EE P2) Derive an expression for the resistances, R'eq and Req, for the small-signal circuit shown below. 2. Relevant equations 3. The attempt at a solution (Attachment 2 - EE P2.1) My thought process is exactly what I have written: Solve for R'eq - First R1 and R2 are in series, and then the result is in parallel with GmVx Req = R'eq in parallel with R3 Any thoughts or input/am I wrong in doing this?
