Need for CMFB
I read somewhere that it is difficult to set the bias point for high impedance nodes and that's why we need CMFB. Would like to understand this intuitively. I understand the concept of 2 fighting current sources, but was wondering if there's more to the bias point of high impedance nodesNot enough info to give you an informed answer.
What exactly, are you trying to bias?
