when a large signal is applied to the input of S/H, the bias voltage and the common mode output voltage of diff-amp may be interfered and shows some fluctuation. increasing the decouple capacitance or bias current may reduce these fluctuation. but how can I ensure that the current or the capacitance is enough? should I keep these fluctuation under certain level? or only need to care about the differential output regardless of these common mode fluctuation?
any calculation method or simulation method?
the paper or other reference would be more I appreciated!
thanks in advance!
