Question 1.
What does differential mode gain measure?
Show hintHide hint
Think about the desired signals.
Question 2.
Describe the purpose of common mode gain in differential amplifiers.
Show hintHide hint
Remember, we want this to be low.
3Question 3.
What does differential mode gain (A_d) measure?
- Output to output ratio
- Differential output to differential input ratio
- Common mode output to input ratio
Show hintHide hint
Focus on what the gain reflects.
4Question 4.
True or False: A high common mode gain is desirable in differential amplifiers.
- True
- False
Show hintHide hint
Think about signal integrity.
Question 5.
An amplifier has A_d = 60 and A_c = 12. Analyze the implications of A_d/A_c and A_c/A_d, and discuss the performance of this amplifier in practice.
Show hintHide hint
Use ratios to assess amplification capabilities.
Question 6.
Explain how you would approach designing a differential amplifier circuit focusing on minimizing A_c.
Show hintHide hint
Think about placement and component types.
