Question 1.
What happens to the drain current if the width (W) of a MOSFET is increased?
Show hintHide hint
Think about how width affects resistance.
Question 2.
What is the threshold voltage (V_th)?
Show hintHide hint
Recall its importance in MOSFET operation.
3Question 3.
What is the relation between channel width and drain current in a MOSFET?
- Increased width results in lower current
- Increased width results in higher current
- Width has no effect on current
Show hintHide hint
Consider the definition of current flow in terms of resistance.
4Question 4.
Pinch-off occurs when the channel's conductivity becomes zero. True or False?
- True
- False
Show hintHide hint
Think about what happens to the channel during pinch-off.
Question 5.
Given a MOSFET with W=10 micrometers and L=1 micrometer, calculate the aspect ratio and explain its significance.
Show hintHide hint
Consider how the ratio impacts device resistance and current levels.
Question 6.
A circuit's V_GS is 5V and V_th is 1V. If V_DS is increased beyond V_th, discuss how the current will behave as it approaches pinch-off.
Show hintHide hint
What does pinch-off tell you about the relationship between voltage and current?
