Question 1
What is the voltage gain equation for a common source amplifier?
- A = V_out / V_in
- A = R_D * g_m
- A = -R_D * g_m
π‘ Hint: Consider how output voltage behaves with respect to input.
Question 2
True or False: The output resistance increases with increasing load resistance.
- True
- False
π‘ Hint: Think about how loading changes the output voltage instead.
