Question 1.
What is the threshold voltage in a MOSFET?
Show hintHide hint
Think about what voltage is needed for current to start flowing.
Question 2.
What happens to the current in the saturation region?
Show hintHide hint
Consider how changes in voltage affect current in this region.
3Question 3.
What is the primary role of threshold voltage in a MOSFET?
- To define the maximum voltage
- To determine device turn-on
- To measure channel length
Show hintHide hint
Think about what voltage is needed for the MOSFET to start operating.
4Question 4.
True or False: In the saturation region, the current changes significantly with V_DS.
- True
- False
Show hintHide hint
Recall the characteristics of the saturation region.
Question 5.
If a MOSFET has a threshold voltage of -1.5V and V_GS = -3V, what happens if V_DS is 0V? Analyze the situation.
Show hintHide hint
Consider what voltage levels are needed for conduction.
Question 6.
Given a n-MOSFET with parameters K = 200 uA/V^2, V_th = 1V, calculate the current I_D when V_GS = 4V and V_DS = 3V, confirming which region it's in.
Show hintHide hint
Ensure you calculate which region the device operates based on the relationship between V_DS and the threshold.
