Challenge Problems
Push your limits with advanced challenges
If an amplifier has a gain of 50 and feedback factor β = 0.1, what will be the gain after feedback is implemented? Further, illustrate this with a Bode plot showing both original and feedback gain.
💡 Hint: Make sure to plot the frequencies correctly on a logarithmic scale.
Discuss a scenario where two poles in a feedback amplifier can lead to instability and how to resolve this issue in design.
💡 Hint: Think about how design choices affect stability in feedback systems.
