Question 1.
What does a differential amplifier amplify?
Show hintHide hint
Think about the name itself.
Question 2.
What are the two types of gain associated with differential amplifiers?
Show hintHide hint
Consider the types of input signal applied.
3Question 3.
What is the primary function of a differential amplifier?
- A. Amplify the sum of two signals
- B. Amplify the difference between two signals
- C. Only amplify AC signals
Show hintHide hint
Focus on what the name implies.
4Question 4.
True or False: The common mode gain of a differential amplifier should be maximized.
- True
- False
Show hintHide hint
Consider what you want to amplify vs minimize.
Question 5.
Design a differential amplifier circuit using both BJT and MOSFET configurations. Compare their performance in terms of gain and noise rejection.
Show hintHide hint
Use characteristics from both components in your design.
Question 6.
In a situation where component matching isn't achievable, discuss how performance would vary in a differential amplifier.
Show hintHide hint
Consider what would happen if components respond differently to input signals.
