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.
