Challenge Problems
Push your limits with challenges.
Question 1
An amplifier has an open-loop gain of 4000 and is configured with a feedback factor of 0.01. What is the closed-loop gain? How would this configuration stabilize the output in a noisy environment?
💡 Hint: Use the closed-loop gain formula correctly.
Question 2
Discuss the implications of having a higher feedback factor in terms of amplifier stability and performance.
💡 Hint: Think about the trade-offs between noise reduction and stability.
