Question 1.
What does MOSFET stand for?
Show hintHide hint
Think about the full form of the acronym.
Question 2.
What is the role of the oxide layer in a MOSFET?
Show hintHide hint
Consider its relationship to the gate.
3Question 3.
What does V_th represent in a MOSFET?
- Voltage at which the MOSFET turns off
- Threshold voltage for channel conduction
- Maximum voltage rating
Show hintHide hint
Consider when the channel moves from insulator to conductor.
4Question 4.
True or False: The structure of a MOSFET includes a metal gate, an oxide insulator, and a p-type substrate.
- True
- False
Show hintHide hint
Think about the definitions we discussed.
Question 5.
A MOSFET with a V_th of 3V operates with a V_GS of 8V. What happens if V_GS is decreased to 2V?
Show hintHide hint
Consider the definition of threshold voltage.
Question 6.
If a certain MOSFET has a width-to-length ratio of 10:1, how does this influence its I-V characteristic?
Show hintHide hint
Think about how area impacts current capacity.
