Question 1.
What is the effect of increasing V_GS on I_DS?
Show hintHide hint
Think about the importance of channel formation.
Question 2.
What does V_th represent?
Show hintHide hint
Recall what happens when V_GS is below this value.
3Question 3.
What does increasing V_GS do to the current in a MOSFET?
- Decreases current
- Increases current
- Has no effect
Show hintHide hint
Link this to channel formation.
4Question 4.
V_th is defined as:
- True
- False
Show hintHide hint
Think about operation thresholds.
Question 5.
A MOSFET has a V_th of 1V. If V_GS is set to 3V and V_DS is increased to 5V, describe the current behavior. What region is the MOSFET operating in?
Show hintHide hint
Link the operating regions to voltage levels.
Question 6.
Demonstrate how the effective channel length changes when V_DS approaches saturation. Explain the impact on I_DS.
Show hintHide hint
Use the relationship between V_DS and channel length to guide your explanation.
