Question 1
What does the voltage gain formula for a CE amplifier look like?
- A_v = g_m * R_C
- A_v = -g_m * R_C
- A_v = g_m / R_C
💡 Hint: Recall how the output signal relates to the input signal in terms of phase.
Question 2
The input resistance of a CE amplifier is determined primarily by which parameter?
- True
- False
💡 Hint: Consider the components connected to the input terminal.
