Challenge Problems
Push your limits with challenges.
Question 1
Given a differential amplifier with resistors that are not equal, derive an expression for the output voltage when both a common mode and differential signal are applied.
💡 Hint: You may need to consider the resistor effects on the overall gain.
Question 2
Evaluate the effects of common mode rejection ratio (CMRR) on the overall functionality of an amplifier if the CMRR is low.
💡 Hint: Look back at the definitions and principles you learned regarding signal integrity.
