Question 1
What is the formula for voltage gain?
- A_v = V_out / V_in
- A_v = V_in / V_out
- A_v = g_m * R_D
💡 Hint: Consider how you measure output in context of input.
Question 2
True or False: Cascading stages decreases overall bandwidth.
- True
- False
💡 Hint: Think about additive benefits of multiple stages.

Challenge Problems
Push your limits with challenges.
Question 1
Design an amplifier with a desired voltage gain of 20 and calculate the required g_m and R_D if you have a 4kΩ resistor available.
💡 Hint: Think of rearranging the gain formula to determine your variables.
Question 2
Given a common source amplifier with a bandwidth of 600 kHz, if you cascade it with a common drain amplifier, achieving a total bandwidth of 3 MHz, what can you conclude about the design efficiency?
💡 Hint: Reflect on how adding stages affects performance metrics.
