Question 1
What is the formula for calculating voltage gain in a common emitter amplifier?
- A = g_m * R_C
- A = -g_m * R_C
- A = g_m + R_C
π‘ Hint: Consider how gain is derived mathematically.
Question 2
True or False: The output swing is unaffected by the amplifier's stability.
- True
- False
π‘ Hint: Think about the constraints on output signal variability.
