Question 1.
Define a differential amplifier in your own words.
Show hintHide hint
Focus on the function of the amplifier.
Question 2.
What does the common mode operation imply about input signals?
Show hintHide hint
Think about the term 'common'.
3Question 3.
What does a differential amplifier primarily do?
- Amplifies a single signal
- Amplifies the difference between two signals
- Rejects all signals
Show hintHide hint
Remember the focus on 'difference'.
4Question 4.
In common mode operation, the output of the differential amplifier is ideally:
- True
- False
Show hintHide hint
Think about identical inputs.
Question 5.
Design a differential amplifier with a desired differential mode gain of 50. You have transistors with varying transconductances; outline your process.
Show hintHide hint
Think about how changes in resistor values affect gain.
Question 6.
If your output signal swing is lower than expected, identify potential factors causing this limitation and discuss how to resolve them.
Show hintHide hint
Think of all variables impacting output performance.
