I have met the problem when design the differential receiver used in USB 1.1 Transceiver,according USB 1.1 spec, the differential sensitive is 200mV ,and Common mode range is 0.8 to 2.5V (include dierential range).
So the comparator is needed to compare the (v2-v1) and 200mV, I used the two differential pair to realize (v2-V1)-(ref2-ref1), (ref2-ref1)=200mV, but the common mode is problem.
thanks a lot for advice about it.
