reduce the charge injuection and clock feedback

In a S/H what you usualy must ensure is that the output voltage gets sufficiently near the ideal value. The way it "gets there" is not very important.

Different s/h circuits, have different way to reducing glitch.as to switch cap s/h circuit, charge injection and clock feedthrough are considered.also opa must have large DC gain.
