Question 1.
Define common mode stimulus in a differential amplifier.
Show hintHide hint
Think about two inputs that are the same.
Question 2.
What is the purpose of a differential amplifier?
Show hintHide hint
Consider how it processes contrasting signals.
3Question 3.
What does common mode gain (A_c) measure?
- Output voltage to input voltage ratio
- Common output voltage to common input voltage ratio
- Differential output voltage to input voltage ratio
Show hintHide hint
Focus on outputs that are the same.
4Question 4.
True or False: The differential amplifier only amplifies the largest input signal.
- True
- False
Show hintHide hint
Think about how differential input works.
Question 5.
Design a differential amplifier that can handle both common and differential signals. Specify values for resistors and power supply.
Show hintHide hint
Consider how varying resistor values affect the overall gain.
Question 6.
Evaluate the impact of component tolerances on the common mode and differential gain of your designed circuit.
Show hintHide hint
Understand the relationship between components and output.
