Question 1
What does an increase in gate voltage above threshold voltage do?
- Decreases output
- Increases output
- Has no effect
💡 Hint: Consider the relationship between gate and output we discussed.
Question 2
True or False: The load line shows the characteristics of the MOSFET.
- True
- False
💡 Hint: Remember what we discussed about load lines versus I-V characteristics.

Challenge Problems
Push your limits with challenges.
Question 1
A MOSFET with K=3 mA/V² and a threshold voltage of 1.8V is connected to a 12V supply. If the gate voltage is set to 2.5V, calculate the drain current and determine if the MOSFET is in saturation or not at R=2K.
💡 Hint: Make sure to check the voltage drop across the resistor as well!
Question 2
Analyze a circuit using an NMOS where the load line intersects with the I-V curve at multiple points—describe the significance of each intersection.
💡 Hint: After finding the intersection points, identify their corresponding output voltages.
