Challenge Problems
Push your limits with challenges.
Question 1
Design a common-source amplifier with the following specifications: Use VDD = 15V, target IDS = 2mA, and Vth = 2V. What resistors R1 and R2 will you choose if you want VGS at 4V?
💡 Hint: Use KVL for voltage drop calculations.
Question 2
If we want to increase the gain of our amplifier while maintaining the same VDD and maximum swing, what design changes would you implement?
💡 Hint: Analyze the relationships between R_D, IDS, and gain.
