Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the formula for voltage gain in a common source amplifier?
- A = R_D * g_m
- A = -R_D * g_m
- A = g_m / R_D
💡 Hint: Remember the relationship between voltage gain and the output resistor.
Question 2
True or False: The input resistance of a common source amplifier is high due to zero gate current.
- True
- False
💡 Hint: Think about what happens at the input port.

Challenge Problems
Push your limits with challenges.
Question 1
Given a common source MOSFET amplifier with a transconductance g_m = 2 mA/V, find the output voltage for an input AC swing of 0.5V, given that R_D = 3 kΩ. Calculate the voltage gain and the expected output swing.
💡 Hint: Use the gain formula learned earlier.
Question 2
Discuss how you would design a common source amplifier to optimize its voltage gain in an integrated circuit environment as compared to discrete circuit designs.
💡 Hint: Think about the trade-offs in real estate versus performance.
