Question 1
What is the voltage gain formula for a common source amplifier?
- Av = gm * RD
- Av = RD / gm
- Av = gm + RD
π‘ Hint: Think again about how gain is derived.
Question 2
True or False: Cascading stages in amplifiers decreases overall bandwidth.
- True
- False
π‘ Hint: Consider the purpose of combining amplifier stages.

Challenge Problems
Push your limits with challenges.
Question 1
Design a cascading amplifier circuit with a common source and a common drain stage. Given load capacitance of 50 pF, calculate the expected upper cutoff frequency if RD is 2 kΞ©.
π‘ Hint: You can change the values and test different configurations for better insight.
Question 2
If the output of the common source amplifier is observed to have a gain of 8 instead of the calculated 6, discuss the potential reasons for this discrepancy.
π‘ Hint: You might want to think about all the factors involved in amplifier performance.
