Dear friends,
So far one of our mentors, Panch told me about excellent source to simulate the fully differential amplifier using Balun, I am using now this instance and giving me good shorcut. One issue I have with simulating the common mode gain (ACM),
attached you see the setup according to the source explanation
Under the AC simulation we probe the VOC which represent the ACM (because the input is 1 V).
My question that generally ACM = VOD/VID where VID are two inphase signal, how this equation is achieved from the proposed setup ?
to have a detail about the setup please read section 3.1 from the below document (suggested by Pancho)

Thank you very much in advance
