Why is it that, fully differential opamps (opamps that have two inputs, two outputs, and one common mode votlage pin) require common mode feedback, but operational floating amplifiers (OFCs) do not need common mode feedback?
--> They both have two inputs and two outputs, but I don't understand why many of the OFCs and four terminal floating nullor (FTFN) circuits that I read about in literature do not have common mode feedback. Any ideas as to why this is?
