Question 1
What is the formula for voltage gain in a common source amplifier?
- A = g_m * R_D
- A = -g_m * R_D
- A = R_D / g_m
💡 Hint: Look for the relationship involving transconductance and resistance.
Question 2
True or False: The output resistance of a common source amplifier is always greater than its input resistance.
- True
- False
💡 Hint: Think about how input and output resistances are defined.
