Question 1

What happens when a positive voltage is applied to the gate of a p-type MOSFET?

  • Holes are attracted
  • Electrons are repelled
  • A depletion region is formed

💡 Hint: Consider how positive voltage interacts with the majority carriers.

Question 2

True or False: The threshold voltage is the maximum voltage at which the channel remains conductive.

  • True
  • False

💡 Hint: Think about what threshold means in general.

Challenge Problems

Push your limits with challenges.

Question 1

Given a p-type MOSFET with a threshold voltage of 1V, describe what happens at 0.5V, 1V, and 2V gate voltages in terms of charge carriers and current flow.

💡 Hint: Analyze how the channel characteristics change with each voltage.

Question 2

Explain how the increase in drain-source voltage affects the operation of an n-MOSFET already in the conductive state.

💡 Hint: Focus on the interrelation between gate voltage, channel conductivity, and current.
