how to deal with s/h kickback

[frederick.im]

recently, i am doing something about ti s/h
i found that parasitic ind became a big problem
pkg, pcb, even smd res & cap
all of them cause ind
so different s/h 's kickback became important
most paper solve this problem by add buffer before ti s/h
to isolate kickback from input

but i think add internal comman resistor maybe another option
kickback absorbedby the internal cm resistor instead by the para ind

but i found little papet about this solution

can anybody give me some papet title about "how to deal with s/h kickback"

Post your circuit diagram.
