Question 1.
What is the primary function of a differential amplifier?
Show hintHide hint
Consider what happens to signals that are the same at both inputs.
Question 2.
Define common mode gain.
Show hintHide hint
Think about the signals that would not change when both inputs are the same.
3Question 3.
What does a differential amplifier primarily do?
- Amplifies a single signal
- Amplifies difference between two signals
- Eliminates all noise
- Creates a common mode signal
Show hintHide hint
Focus on what makes differential amplifiers special.
4Question 4.
True or False: High common mode gain is desirable in a differential amplifier.
- True
- False
Show hintHide hint
Think about noise contamination.
Question 5.
Design a differential amplifier with a desired differential gain of 100. Discuss how you would minimize the common mode gain to ensure signal clarity.
Show hintHide hint
Research design techniques for improving amplifier performance.
