I want to level shift one voltage Vin up by one Vthn0 (threshold voltage of NMOS when Vgs=0), I am not sure how to use NMOS to realize it? Thank you very much!
 

i m not sure but u can use source follower and then summer to do your job.
 

thanks vbhupendra. yes, by using SF, voltage can be shift up by Vgs or several Vgs, but one problem, how to avoid the body effect. conventional process donot support isolated p-well, i think that is a problem.
