Challenge Problems
Push your limits with challenges.
Question 1
Design a common source amplifier for a desired output voltage swing of +/- 3V using Vdd = 12V and a threshold voltage of 1V. Determine the values of R1, R2, and RD.
💡 Hint: Break down the design based on maintaining balance around the center voltage.
Question 2
What will happen to the output gain if RD is increased without changing VGS? Explain and calculate.
💡 Hint: Look into the effects on gain per the transistor’s equations to fully understand this.
