Isn't the whole PMOS (I mean N-tub) buried in P-substrate anyway? In the case when N-tub is Vcc biased, and P-substrate ground biased, that is the usual situation, isn it?Colbhaidh said:So the most important thing is to consider any PMOS in (N Diff) could become close to an PWell biased at 0 Volts. Worst case, the N Diff would be at the Vcc supply to the pmos transistors.
