Challenge Problems
Push your limits with challenges.
Question 1
Design a common emitter amplifier using feedback where the input resistance needs to be calculated knowing the feedback network offers a gain of 10. How would you approach this?
💡 Hint: Recall how feedback reduces input resistance.
Question 2
If a feedback network affects both the gain and input resistance of an amplifier, explain how you'd validate the effectiveness of stability with specific resistance values.
💡 Hint: Integrate your knowledge about feedback resistance relationships.
