Question 1.
What does a differential amplifier accomplish?
Show hintHide hint
Think about the two input signals.
Question 2.
Define differential mode gain.
Show hintHide hint
What part of the input does it amplify?
3Question 3.
What is the main function of a differential amplifier?
- To amplify only a single signal
- To amplify the difference between two signals
- To reduce noise
Show hintHide hint
What do we want the amplifier to do with its inputs?
4Question 4.
True or False: The common mode gain should be maximized for effective performance.
- True
- False
Show hintHide hint
Consider why we want low common mode effects.
Question 5.
Design a circuit using a differential amplifier with specified gain requirements that minimizes common mode influence at the output.
Show hintHide hint
Consider how resistor configurations influence the overall gains.
Question 6.
Evaluate how the introduction of an external noise source affects the performance of a differential amplifier operating in a critical application.
Show hintHide hint
Explore filtering techniques that could manage this noise.
