i guess this circuit is an amplifer,but it 's some different from conventional amp
this circuit is a part of a fold-cascode amp,if it's an amp,then it's a booster
it 's used to generate the biase voltage of the pmos cascode.in1 and in2 is the sources of the two pmos cascode transistor.out1 and out2 is connected to the gate of the two pmos cascode transistor.
but if it's an amp,why not the cmfb circuit.in my opinion,fully differential amp must have the cmfb circuit.
plese help me,any answer is welcome!
thanks
