The variation of drain current with gate-to-source voltage of a MOSFET is shown in fig.The MOSFET is (GATE-EE-2003)
A. an n-channel depletion mode device
B. an n-channel enhancement mode device
C. a p-channel depletion mode device
D. a p-channel enhancement mode device
ANSWER: C
It is the transfer characteristics of a depletion mode device and it must be p-channel, since the Vgs is positive in p-channel depletion region.
