Challenge Problems
Push your limits with advanced challenges
Design a feedback amplifier given specific initial gain and pole locations. How would you modify its structure to enhance stability?
💡 Hint: Use the transfer function to determine how varying feedback affects pole locations.
Consider a dual-pole amplifier where both poles are close to the instability threshold. What feedback modifications could you propose to rectify this?
💡 Hint: Evaluate the relationship of gain versus frequency response to decide on suitable compensatory actions.
