Challenge Problems

Push your limits with challenges.

Question 1

A voltage amplifier has an open-loop gain of 150 and a feedback factor of 0.05. Calculate the closed-loop gain and the output resistance given an input resistance of 2k Ohms and a feedback resistance of 1k Ohms.

💡 Hint: Use formulas for gain and resistance considering feedback components.

Question 2

Design a feedback circuit for a trans-conductance amplifier that ensures stable output characteristics with finite input resistance. What design modifications would you propose to maintain performance?

💡 Hint: Think about how you can balance input/output resistances effectively.
