you can calculate the input mosfet size ,and calculate the offset by it , for the .35um process , the vth will induce the offset of 10mv/sqrt(area of input device)

Dear all,
I have a fully-differential opamp as shown below.
I want to calculate the systematic offset of this opamp by hand, but I don't know how to do.
Please help me if you know. Thanks.
Please, be specific and tell us your DEFINITION of SYSTEMATIC offset.
I remember several book authors who are using the term "systematic offset" even for the BJT voltage Vbe≈0.7 volts (in contrast to other amplifying devices with no or only negligible input differential voltage).
