@ mixed signal, To reduce the non-linearity due to bulk node , you can do the following.
During the hold phase connect the bulk to ground and during the sampling phase, connect the bulk to input.
So, during the sampling mode ur Vbs=0 and hence u dont see any non-linearity. Also in the hold mode, ur bulk is tied to ground so that no junction diode is forward biased independent of input signal level.
