Question 1.
What is the primary charge carrier in a p-MOSFET?
Show hintHide hint
Think of the opposite of electrons.
Question 2.
What type of voltage is required at the gate of a p-MOSFET for it to conduct?
Show hintHide hint
Consider the biasing that enables conduction.
3Question 3.
What is the main charge carrier in a p-MOSFET?
- Electrons
- Holes
- Both
Show hintHide hint
Memorize the difference in charge carriers.
4Question 4.
Is the threshold voltage important for p-MOSFET operation?
- True
- False
Show hintHide hint
Consider what happens if the threshold voltage is not met.
Question 5.
A design requires two p-MOSFETs in series. If the first has a threshold voltage of -2V and the second -3V, what biasing voltage range should you consider to ensure proper operation?
Show hintHide hint
Recall that both devices need to meet their threshold voltage to operate correctly.
Question 6.
Given a p-MOSFET has a mobility of 400 cm^2/Vs, a channel length of 10 μm, and a threshold voltage of -1V. Calculate the expected drain current if a gate-source voltage of -2V is applied.
