Question 1
What does common mode gain represent in a differential amplifier?
- Amplification of different signals.
- Amplification of the same signal across both inputs.
- Ratio between output and input.
💡 Hint: Look for the term 'common' in the definition.
Question 2
True or False: A higher Common Mode Rejection Ratio (CMRR) indicates a more effective amplifier.
- True
- False
💡 Hint: Think about the relationship between amplification and noise rejection.

Challenge Problems
Push your limits with challenges.
Question 1
Analyze a differential amplifier circuit with BJTs and determine the CMRR given specific common and differential mode gains. How does this affect your design considerations?
💡 Hint: Assess how the input signal impacts each gain type.
Question 2
Create a schematic of a differential amplifier using MOSFETs with an active load. Calculate the expected gains.
💡 Hint: Pay attention to how active loads influence the output characteristics.
