MOS transistors can be of
-
Enhancement type
-
Depletion Type
-
Both a and b
-
Neither a nor b
C
Correct answer
Explanation
MOS transistors are indeed classified into two main types: Enhancement type and Depletion type. Enhancement type transistors have no channel initially and require gate voltage to create one. Depletion type transistors have a pre-existing channel that can be depleted. Both types are fundamental to MOSFET technology.
