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

2. Relevant equations

- Adiff(single-ended)= 1/2gm*ro||Rd
- β=R2/(R1+R2)

3. The attempt at a solution

I am really confused as to how to find A. I know the feedback of the circuits around the R2 and R1, but I dont understand how the open loop gain can be found. Can someone assist me in deriving it? First question is what gain are they asking for: common mode or differential? I assume differential, but I am honestly lost.
