Challenge Problems
Push your limits with challenges.
Question 1
If you have two input voltages V1 = 12V and V2 = 8V with a differential amplifier gaining 6, what will be the output voltage? Further, if a common mode voltage of 4V is also applied, what is the effect on the output?
💡 Hint: Focus on using the gain formula and think about what common voltage implies.
Question 2
Discuss the practical implications if a differential amplifier has a very low CMRR. How would that affect its application in a noisy environment?
💡 Hint: Think about how noise can affect communication clarity in electronic devices.
