Question 1

What is the voltage gain formula for a common source amplifier?

  • Av = gm * RD
  • Av = RD / gm
  • Av = gm + RD

💡 Hint: Think again about how gain is derived.

Question 2

True or False: Cascading stages in amplifiers decreases overall bandwidth.

  • True
  • False

💡 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 kΩ.

💡 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.

💡 Hint: You might want to think about all the factors involved in amplifier performance.
