When simulating the SR or OS of the differential amplifier,should I take away the CMFB circuit ???
 

Dear ronanchang,
Does OS stand for output swing
 

yes,the OS stands for output-swing
 

I think it does not need
 

Hi,

You cannot take away CMFB circuit when you try to simualte the differiential opamp's slew rate and output swing. If so, the opamp will not work properly and you will get the wrong value.

Hope it helps.
