How the Capicitor effect the poles of op-amp

tandr

Hi every one :
    I saw that many  op-amp's input stage  have a capicitor connected between
one of the differential output and VDD (see the below graph.) Besides this
capicitor ,  there are other Miller capicitors in the op-amp ,for example capicitor
connected between the output and the other differential output of the input
stage .
   If there is not the capicitor in the input stage connected between VDD and
one of the output of the first stage , the poles in the op-amp can be calculated
easily by Miller theory. But I don't know how the capicitor in the graph below
effect the other poles and how to calculate the pole of this capicitor .
Is there some one can help me .
