Challenge Problems
Push your limits with advanced challenges
A differential amplifier has a differential gain of 50 and a common mode gain of 0.1. If the differential input is 3V, what is the output voltage? What would the common mode output be if the common mode input is 10V?
💡 Hint: Multiply the gains by the respective inputs.
Critically analyze what happens when a differential amplifier's common mode gain increases unexpectedly. How does it affect signal quality?
💡 Hint: Consider the implications of noise in your analysis.
