6 sample questions

Question 1.
What is the formula for voltage gain?
Show hintHide hint
Think about how output and input relate to each other.
Question 2.
What does the negative sign in voltage gain represent?
Show hintHide hint
Consider how the input signal behaves relative to the output.
3Question 3.
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
Show hintHide hint
Consider how output voltage behaves with respect to input.
4Question 4.
True or False: The output resistance increases with increasing load resistance.
- True
- False
Show hintHide hint
Think about how loading changes the output voltage instead.
Question 5.
Calculate the voltage gain for a common source amplifier if R_D = 10 kΩ and g_m = 1 mA/V. What implications does the gain level present?
Show hintHide hint
Use A = -R_D * g_m to find the gain.
Question 6.
Discuss how increased output resistance affects amplifier behavior when connected to different loads.
Show hintHide hint
Focus on the implications of Ohm's Law in signal transfer.
