i am designing one using 65nm tech. but i could not find the breakdown voltage for the source/drain junction, and i am not sure how high it can experience without breakdown. with a 1.2V supply, one of the transistors in the charge-pump part experiences a 2.3-1.2v swing, is it safe?
The question you are asking is very unique to the particular foundry process.
Find out the limitations from the foundry.
