I wish I could explain it, but I don't understand it well myself. Add a comment. Active Oldest Votes. Although it introduces body effect and makes transistors slower and deviate from ideal mos current equation, there is no other way.

One could achieve different body voltage for all nmos transistors by putting all transistors in different wells, but that would mean a tremendous penalty in terms of area as there needs to be minimum size and separation that needs to be maintained which is huge in comparison to transistor sizes.

This is the reason why body is connected to ground for all NMOS.
