Challenge Problems
Push your limits with challenges.
Question 1
Given a differential amplifier with a differential mode gain of 50, a common mode gain of 0.1, and input voltages of 2V (differential) and 10V (common mode), calculate the output voltage.
💡 Hint: Apply the gains to each signal input.
Question 2
If common mode signals are affecting outputs significantly, what design changes would you implement to minimize their impact?
💡 Hint: Think about component selection and circuit layout.
