Question 1.
What does MOSFET stand for?
Show hintHide hint
Think about its application in electronics.
Question 2.
What is V_th in reference to MOSFET?
Show hintHide hint
Consider the minimum voltage necessary to activate the MOSFET.
3Question 3.
What is the threshold voltage (V_th) in a MOSFET?
- Minimum voltage to create a channel
- Maximum voltage for saturation
- Voltage drop across the device
Show hintHide hint
Think about what initiates the functioning of a MOSFET.
4Question 4.
In which region does the current remain relatively constant despite changes in V_DS?
- Triode region
- Saturation region
- Off region
Show hintHide hint
Remember the characteristics of operational states.
Question 5.
A MOSFET has a threshold voltage of 2V. Given V_GS = 5V and V_DS = 3V, calculate the current with K = 0.5 and comment on the operating region.
Show hintHide hint
Consider if V_DS affects your calculations.
Question 6.
Explain how increasing the dielectric constant would impact the current in a MOSFET.
Show hintHide hint
Think about how capacitive effects can help current movement.
