Challenge Problems
Push your limits with challenges.
Question 1
Given a differential amplifier setup with input voltages of 3V and 1V, and a gain of 50, calculate the output voltage. Discuss how this exemplifies differential operation.
💡 Hint: Focus on the gain impacting the difference, not the individual inputs.
Question 2
Evaluate a scenario where a common mode voltage of 5V is applied to both inputs of a differential amplifier designed to amplify 1V differences. How may this affect signal processing?
💡 Hint: Recall how common-mode operation works.
