Challenge Problems
Push your limits with challenges.
Question 1
If a differential amplifier shows a differential gain of 40 and a common-mode gain of 0.1, what is the CMRR? Discuss how you would verify this using measurements.
💡 Hint: Use basic gain measurement techniques you've learned.
Question 2
In a scenario where your Op-Amp is configured with a feedback resistor of 20kΩ and an input resistor of 5kΩ, what would be your predicted gain, and how does it relate to the bandwidth?
💡 Hint: Derive the relationship between gain and bandwidth as discussed.
