Question 1.
Define common mode gain in your own words.
Show hintHide hint
Think about what it means for signals to be present at both inputs.
Question 2.
What role does a current mirror play in amplifiers?
Show hintHide hint
Consider how it might ensure consistent operation.
3Question 3.
What is common mode gain?
- Gain for individual signals
- Gain for signals common to both inputs
- Gain for differential signals
Show hintHide hint
It relates to both inputs of the amplifier.
4Question 4.
True or False: A current mirror increases the common mode gain in an amplifier.
- True
- False
Show hintHide hint
Think about how current mirrors affect stability.
Question 5.
Given a circuit with a specific transconductance value and output resistance, calculate the common mode gain and describe its implications for signal processing.
Show hintHide hint
Make sure you understand the relationship and its effects on circuit functionality.
Question 6.
Analyze a complex amplifier configuration with two different current mirrors and derive the overall common mode gain.
Show hintHide hint
Consider the roles of each current mirror distinctly and how they contribute to the overall performance.
