Why is PMOS always placed above NMOS? A、a)PMOS produces weak one and NMOS produces strong zero B、b)PMOS produces weak one and NMOS produces weak zero C、c)PMOS produces strong one and NMOS produces strong zero D、d)PMOS produces st
This is why most sampling circuits use two FETs, one NMOS and one PMOS, to make what is known as a transmission gate. The configuration you show should only be used if the circuit it is a part of constrains the signals to levels that will turn the FET on hard when it is "closed"....
