Question 1.
What is a differential amplifier?
Show hintHide hint
Think about what it does with two signals.
Question 2.
What happens to the signals in common mode when using a differential amplifier?
Show hintHide hint
Consider the noise aspect.
3Question 3.
What does a differential amplifier primarily amplify?
- Common-mode signals
- The difference between two input signals
- Only the noise
Show hintHide hint
Focus on what differentiates this amplifier from others.
4Question 4.
True or False: A common-mode signal is desired in a differential amplifier.
- True
- False
Show hintHide hint
Consider whether we want noise or clarity.
Question 5.
A differential amplifier has an input of 0.1V across one pin and 0.02V on the other pin. If the differential mode gain is 200, what would be the output voltage?
Show hintHide hint
Calculate the difference first, then apply the gain.
Question 6.
Describe how you would design an amplifier to reduce the impact of high common-mode signals in a noisy environment.
Show hintHide hint
Consider practical design strategies and apply concepts learned.
