Challenge Problems

Push your limits with challenges.

Question 1

Given a feedback amplifier with an ideal gain of 100, input resistance of 1kΩ, and output resistance of 4kΩ. If the source resistance increases to 50Ω, what will be the new effective output resistance?

💡 Hint: Ponder the voltage division concept for practical application.

Question 2

Design a trans-impedance amplifier circuit that maintains output resistance below 1kΩ while introducing a source resistance of 100Ω. Explain how to achieve this design goal.

💡 Hint: Consider feedback loops and resistance combinations for desensitization.
