Challenge Problems
Push your limits with challenges.
Question 1
For a p-channel MOSFET with a threshold voltage of -2V, calculate the drain current with a gate-source voltage of -5V and a drain-source voltage of -10V, given a mobility coefficient of 200 cm²/V·s.
💡 Hint: Pay close attention to the relationship between threshold and applied voltages.
Question 2
Explain how varying the channel dimensions affects the current in a p-channel MOSFET. Provide practical examples.
💡 Hint: Remember that current increases with conductivity, which improves with dimension tuning.
