Question 1.
What is a single-ended amplifier?
Show hintHide hint
Think about the basic setup of amplifiers.
Question 2.
Define differential gain.
Show hintHide hint
Consider what we’re amplifying in a differential amplifier.
3Question 3.
What does a single-ended amplifier compare its signal to?
- A differential signal
- A common ground
- Both inputs
Show hintHide hint
Remember the basic principle of its operation.
4Question 4.
True or False: Differential amplifiers focus solely on the common mode signal.
- True
- False
Show hintHide hint
Recall the definition of a differential amplifier.
Question 5.
Design a circuit that could benefit from using a differential amplifier rather than a single-ended amplifier. Justify your design choice.
Show hintHide hint
Think about where noise tends to interfere in signals.
Question 6.
Calculate the differential gain if the input difference is 0.5V and the output is 5V.
Show hintHide hint
Use the formula for gain proportionally related to output and input difference.
