Question 1

What is the primary effect of feedback on an amplifier's frequency response?

  • It decreases the input impedance
  • It stabilizes the gain
  • It always increases the gain

💡 Hint: Reflect on how amplifiers maintain their output performance.

Question 2

True or False: Feedback can destabilize an amplifier if not properly implemented.

  • True
  • False

💡 Hint: Consider the behavior of systems under external modifications.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
