Sizing of switches in Integrator

[ruby1212]

Hello all,
My question is about the considerations of sizing the switches in the integrator of the attached photo with respect to the values of capacitors C1 and C2:
The switches marked as S1 (those of the first phase) should be different in size with respect to the switches of the second phase (marked as S2) ?
If the ratio C2/C1 is equal to 100, how should the dimensions of the switches follow ? (Of course, I am talking about mos transistor switches),
Thanks in advance for your answers!

Should they? I don't think so. There's no relation of switch phases to capacitor ratio, but I can imagine reasons to use balanced switches sizes, e.g. compensation of charge injection.
