Challenge Problems
Push your limits with advanced challenges
If the output from a differential amplifier is given to be 20V and the differential gain is determined to be 4, what are the possible values of the two input signals?
💡 Hint: Think about how to rearrange the output equation.
You have two signals, V1 = 7V and V2 = 3V. If the common mode gain is observed to be 0.5, what implications does this have for the noise level?
💡 Hint: Identify how common mode affects the signals.
