Question 1.
What does differential mode gain (Ad) measure?
Show hintHide hint
Think about what we want to amplify in differential signals.
Question 2.
What is meant by common mode gain (Ac)?
Show hintHide hint
Consider the type of noise that affects both inputs.
3Question 3.
What is differential mode gain (Ad)?
- A measure of noise amplification
- The amplification factor for the difference between two signals
- The average signal from two inputs
Show hintHide hint
Focus on what Ad specifically deals with.
4Question 4.
True or False: Common mode gain should be as high as possible for optimal amplifier performance.
- True
- False
Show hintHide hint
Think about the role of common mode signals.
Question 5.
Design a differential amplifier circuit that minimizes the common mode gain while maximizing differential gain.
Show hintHide hint
Consider component choices and circuit layout.
Question 6.
Analyze how varying input signals can affect the output of a differential amplifier with non-ideal gains.
Show hintHide hint
Think about gain ratios in your analysis.
