The Transfer characteristic of the different types of MOSFETs is shown below, where ID is drain current and VGS is the Gate-Source voltage, the correct combination of MOSFET w.r.t to transfer characteristics is:
Types of MOSFET
(P) P – Channel Enhancement MOSFET
(Q) P – Channel Depletion MOSFET
(R) N – Channel Enhancement MOSFET
(S) N – Channel Depletion MOSFET
1
P – 4, Q – 2, R – 1, S – 3
2
P – 3, Q – 2, R – 4, S – 1
3
P – 1, Q – 3, R – 2, S – 4
4
P – 2, Q – 4, R – 3, S - 1
