Question 1

What is the formula for CMRR?

CMRR = A_d * A_{cm}
CMRR = |A_d| / |A_{cm}|
CMRR = A_d + A_{cm}

💡 Hint: Think about what it really means to measure how signals are amplified.

Question 2

High CMRR is desirable in amplifier design.

True
False

💡 Hint: Consider how noise impacts signal clarity.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have a differential amplifier with A_d = 200 and A_{cm} = 5. Calculate the CMRR and express it in dB.

💡 Hint: Use both the ratio formula and the logarithmic conversion carefully.

Challenge 2 Hard

Discuss the effects of component mismatches in a differential amplifier on CMRR. Provide examples.

💡 Hint: Consider how each component contributes to the overall gain.
