Hi All
I have a folded cascode amplifier. When i run an AC analysis with CMFB (its a transistor based CMFB which i wud replace later by SC-Cmfb) i get a gain of 60dB and UGF of around 55MHz.
But if i remove cmfb, and just connect load capacitance, i get gain of only 30dB and UGF of 35MHz.
Can someone suggest me why is that and which one should i consider correct.
