EEE334 CHAPTER 5 MOS LARGE
SIGNAL OPERATION. EXAM
QUESTIONS AND ANSWERS 100% PASS
What does MOSFET stand for? - ANS Metal Oxide Semiconductor Field Effect Transistor
What are the three terminals of a MOSFET? - ANS A: Gate (G), Drain (D), Source (S)
How does an NMOS transistor turn ON? - ANS A: A positive gate voltage creates an electron
channel, connecting the drain to the source.
Q: What are the two main types of MOSFETs? - ANS A: NMOS (normally OFF, turns ON with
positive VGV_GVG) and PMOS (normally ON, turns OFF with positive
Q: What is the function of the oxide layer in a MOSFET? - ANS A: It insulates the gate from
the substrate, allowing voltage control without direct conduction.
Q: What happens when no voltage is applied to the gate of an NMOS MOSFET? - ANS A: The
MOSFET remains OFF because no conduction channel is formed.
Q: What determines the amount of current a MOSFET can carry? - ANS A: The width-to-
length ratio (W/LW/LW/L) of the channel.
