Challenge Problems
Push your limits with challenges.
Question 1
If a circuit has a MOSFET with V_DD = 12V, R_D = 2kΩ, and the MOSFET has a transconductance parameter K = 0.3 mA/V² and V_th = 1.5V, calculate the output voltage when Vgs = 5V.
💡 Hint: Break the problem into steps: Find current first, then use it to find voltage.
Question 2
Analyze a simple MOSFET amplifier circuit where the input signal causes the Vgs to vary. Discuss how variations affect the class of amplifier operation and performance.
💡 Hint: Think about the conditions leading to saturation and cut-off in response to input changes.
