Practice Questions
Test your understanding with targeted questions
What is the definition of threshold voltage?
💡 Hint: Remember, it's like the gate's password.
What region does a MOSFET operate in when V_DS is less than (V_GS - V_th)?
💡 Hint: Think of it as behaving like a variable resistor.

What is the cutoff region?
💡 Hint: Think about when the switch is off.
In which region does the MOSFET act like a constant current source?
💡 Hint: Where does the current stop changing much with increasing voltage?

Challenge Problems
Push your limits with advanced challenges
Consider a scenario where a MOSFET is operating at its threshold voltage with K = 1.2 mA/V² and applying a V_GS just equal to V_th. Determine the drain current I_DS and explain what happens if V_DS is subsequently increased.
💡 Hint: Think about operating just at the boundary conditions.
A p-MOSFET has V_th = -2V, and you apply V_GS = -4V. If V_SD is increased beyond the saturation point, determine what happens to the drain current.
💡 Hint: Focus on maintaining the larger negative voltages and their effects.
