Question 1

What does CMRR stand for?

Common-Mode Rejection Ratio
Common-Mode Resistance Ratio
Corrective Mode Rejection Rate

💡 Hint: It's related to how well an Op-Amp ignores common signals.

Question 2

True or False: The output stage of an Op-Amp is designed to have high output impedance.

True
False

💡 Hint: Think about what kind of resistance is needed to drive a load.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Explain how imperfections in an Op-Amp's differential stage can lead to common-mode signals being amplified improperly. What designs can mitigate this effect?

💡 Hint: Consider how the characteristics of each component interact.

Challenge 2 Hard

Design a simple Op-Amp circuit using all three stages discussed. Detail how each stage influences performance.

💡 Hint: Think sequentially about what each stage must accomplish.
