3Question 3.
What does differential mode gain measure?
- Amplification of input signals
- Ratio of output to input for differential signals
- Measurement of noise reduction
Show hintHide hint
Look back at the definitions we've discussed.
4Question 4.
True or False: Common mode signals are those that affect only one input of the differential amplifier.
- True
- False
Show hintHide hint
Think about the nature of common mode signals.
Question 5.
Design a differential amplifier circuit to achieve a differential gain of 100, ensuring the common mode gain remains at 5V. What measures will you implement?
Show hintHide hint
Think about how component choice and layout can impact common mode rejection.
Question 6.
Given an amplifier with differential gain of 75 and common mode gain of 15, calculate the CMRR and discuss its implications on signal quality.
Show hintHide hint
Recall the CMRR formula and how to interpret its values in practical scenarios.
