Question 1.
What is a differential amplifier?
Show hintHide hint
Think about its primary function.
Question 2.
Explain what is meant by common mode gain.
Show hintHide hint
Relate this to the concept of noise.
3Question 3.
What is the main function of a differential amplifier?
- To amplify a single signal
- To amplify the difference between two signals
- To measure voltage levels
Show hintHide hint
Think about what makes it different from other amplifiers.
4Question 4.
True or False: The common mode gain should ideally be as high as possible.
- True
- False
Show hintHide hint
Reflect on the definitions we've discussed.
Question 5.
You are designing a differential amplifier with an ideal differential mode gain of 100 and a common mode gain of 0.01. If the input signals are 0.2V and 0.1V, what is the expected output?
Show hintHide hint
Focus on the gain calculations.
Question 6.
How will the performance of your mixed signal (both common mode and differential) be impacted if your differential amplifier is not properly biased?
Show hintHide hint
Consider the impact of bias in circuit operations.
