Question 1.
What is the main function of a differential amplifier?
Show hintHide hint
Think about what the amplifier is focusing on with respect to its inputs.
Question 2.
Define common mode gain.
Show hintHide hint
Consider how this gain affects the efficiency of the amplifier.
3Question 3.
What characterizes a differential amplifier?
- Amplifies only common mode signals
- Amplifies the difference between two input signals
- Noisy signals only
- Single-ended signal output
Show hintHide hint
Focus on what the amplifier is designed to do.
4Question 4.
True or False: The common mode gain should be as high as possible for effective operation.
- True
- False
Show hintHide hint
Consider the effects of common mode signals.
Question 5.
Consider a differential amplifier that has a differential gain of 100 and a common mode gain of 2. If both input signals have a common voltage of 5V and are fed with differential signals of 1V each, what will be the output voltage?
Show hintHide hint
Think about how both gain types affect the overall output.
Question 6.
Suppose you are tasked with designing a differential amplifier for a sensitive audio application. Discuss and propose two design considerations you would prioritize to ensure high signal integrity.
Show hintHide hint
Reflect on factors affecting audio signal quality.
