Question 1.
What does a differential amplifier amplify?
Show hintHide hint
Think about what makes it different from other amplifiers.
Question 2.
What should the common mode gain ideally be?
Show hintHide hint
Remember what we want to minimize in common mode signals.
3Question 3.
What is the main function of a differential amplifier?
- Amplifying single input
- Amplifying the difference between two inputs
- Rejecting all signals
Show hintHide hint
Think about how it compares inputs.
4Question 4.
True or False: A high common mode gain is desirable in differential amplifiers.
- True
- False
Show hintHide hint
Reflect on what we discussed about signal clarity.
Question 5.
Design a differential amplifier using BJTs and specify how you would ensure component matching.
Show hintHide hint
Think about the specifications and how component values influence performance.
Question 6.
Given that Ad = 75 and Ac = 3, discuss the implications of these values on performance in a real-world setting.
Show hintHide hint
Consider the applications where clarity is essential.
