Challenge Problems
Push your limits with challenges.
Question 1
An amplifier has a pole at p = 1 kHz. After introducing a feedback factor Ξ² = 0.1, what is the new pole location?
π‘ Hint: Plug in the values directly into the equation.
Question 2
For an amplifier with one pole at p = 1 kHz and feedback that maintains Ξ² less than 1, explain how the stability bandwidth changes.
π‘ Hint: Consider how reduction in gain can influence the frequency stability.
