Challenge Problems

Push your limits with challenges.

Question 1

An n-channel enhancement-mode MOSFET has a threshold voltage of 3V and a gain factor k of 0.5 mA/V^2. Calculate the drain current (ID) when VGS is 5V in the saturation region.

πŸ’‘ Hint: Focus on plugging in the values correctly into the formula.

Question 2

If VGS is increased gradually past the threshold voltage, how would you expect the ID to behave in the different operating regions?

πŸ’‘ Hint: Think about the relationship between VGS and the conductive channel's behavior.
