Is it mandatory tht we should connect source of nmos to ground ? can't drain of nmos b grounded? ... pls tell reason behind connections. :grin:

In my understanding, the purpose of having source and drain is to get a good ohmic contact. Electrons that flows through the channel are provided by power supply not source. In symmetrical MOSFET, both source and drain are same. This naming convection is used for our understanding. The terminal at lower potential is treated as source and terminal at higher potential is called drain.
In case of NMOS yes, source provides the electrons, but what about PMOS case, are you telling here source again provides electrons.If you see MOSFET only, it seems electrons are coming from source and collected at drain.

I understand , MOSFET is uni carrier devices, current flows by either holes or by electrons. NMOS case source provides electrons, PMOS case , source provides holes.
