Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
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
💡 Hint: Consider the definition of current flow in terms of resistance.
Question 2
Pinch-off occurs when the channel's conductivity becomes zero. True or False?
- True
- False
💡 Hint: Think about what happens to the channel during pinch-off.

Question 1
Given a MOSFET with W=10 micrometers and L=1 micrometer, calculate the aspect ratio and explain its significance.
💡 Hint: Consider how the ratio impacts device resistance and current levels.
Question 2
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.
💡 Hint: What does pinch-off tell you about the relationship between voltage and current?
