Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If a differential amplifier has an input of V_in1 = 5V and V_in2 = 1V, calculate the V_id and explain how it contributes to signal amplification.

💡 Hint: Remember the basic formula for calculating differences.

Challenge 2 Hard

Discuss how the common-mode input can adversely affect amplifier performance in a noisy environment and propose a method to mitigate this issue.

💡 Hint: Consider how you could improve circuit design to handle noise.
