Question 1.
What is a differential amplifier?
Show hintHide hint
Think about what it does with two input signals.
Question 2.
What does common mode rejection mean?
Show hintHide hint
Consider why we want to eliminate certain signals.
3Question 3.
What is the main purpose of a differential amplifier?
- To amplify a single signal
- To amplify the difference between two signals
- To eliminate all signals
Show hintHide hint
Focus on what the amplifier is supposed to do with two inputs.
4Question 4.
True or False: Operational amplifiers can function as differential amplifiers.
- True
- False
Show hintHide hint
Think of the basic definition of op-amps.
Question 5.
Using the principles of differential amplifiers, explain how you would design a sensor circuit that must operate effectively in a noisy environment.
Show hintHide hint
Consider both the input stage and post-amplification processes.
Question 6.
Analyze a scenario where a differential amplifier's output is corrupted due to excessive common mode gain. What design optimizations would help mitigate this issue?
Show hintHide hint
Look at how to improve the overall amplifier design.
