Challenge Problems
Push your limits with challenges.
Question 1
Given a feedback amplifier with an ideal gain of 100, input resistance of 1kΞ©, and output resistance of 4kΞ©. If the source resistance increases to 50Ξ©, what will be the new effective output resistance?
π‘ Hint: Ponder the voltage division concept for practical application.
Question 2
Design a trans-impedance amplifier circuit that maintains output resistance below 1kΞ© while introducing a source resistance of 100Ξ©. Explain how to achieve this design goal.
π‘ Hint: Consider feedback loops and resistance combinations for desensitization.
