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.

πŸ’‘ 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?

πŸ’‘ Hint: Think about component selection and circuit layout.
