EEE334 chapter 5 MOS Large Signal Operation | Questions
with 100% Verified Answers | Latest Update 2026/2027
Question: What does MOSFET stand for?
Answer: Metal Oxide Semiconductor Field Effect Transistor
Question: What are the three terminals of a MOSFET?
Answer: A: Gate (G), Drain (D), Source (S)
Question: How does an NMOS transistor turn ON?
Answer: A: A positive gate voltage creates an electron channel, connecting the drain to the
source.
Question: Q: What are the two main types of MOSFETs?
Answer: A: NMOS (normally OFF, turns ON with positive VGV_GVG) and PMOS (normally ON,
turns OFF with positive
Question: Q: What is the function of the oxide layer in a MOSFET?
Answer: A: It insulates the gate from the substrate, allowing voltage control without direct
conduction.
Question: Q: What happens when no voltage is applied to the gate of an
NMOS MOSFET?
Answer: A: The MOSFET remains OFF because no conduction channel is formed.
Question: Q: What determines the amount of current a MOSFET can
carry?
Answer: A: The width-to-length ratio (W/LW/LW/L) of the channel.
Question: Q: What are the three configurations for MOSFET amplifiers?
Answer: A: Common source, common gate, common drain.
Question: Q: What is Moore's Law in relation to MOSFETs?
Answer: A: It predicts the doubling of transistors on a chip approximately every two years.
Question: Q: Why are MOSFETs preferred over BJTs in digital circuits?
Answer: A: They consume less power and are easier to integrate into large-scale circuits
(CMOS
technology).
Question: Q: What is the purpose of a parasitic diode in a MOSFET?
Answer: A: It forms due to the pn-junctions but is kept reverse-biased to prevent unwanted
conduction.
