Question 1
What is the differential gain (A_d) of a differential amplifier?
- The gain when a common signal is applied
- The gain calculated only with positive voltages
- The gain of the voltage difference between two inputs
💡 Hint: It's based on the difference inputs!
Question 2
Is a higher CMRR more desirable in differential amplifiers?
- True
- False
💡 Hint: Think about noise and clarity of the output signal.

Challenge Problems
Push your limits with challenges.
Question 1
A differential amplifier is designed with a differential gain of 100 and a common-mode gain of 0.2. If the CMRR is calculated, determine its value in dB.
💡 Hint: Use the CMRR formula to find the ratio.
Question 2
Explain why operating outside the ICMR can lead to distortion in signal output. Support your answer with examples of conditions that can cause this.
💡 Hint: Consider operational conditions in practical circuits.
