Challenge Problems
Push your limits with challenges.
Question 1
You have a differential amplifier with two inputs, one at 3V and the other at 1V. If the common-mode gain is 1, what would the output voltage when the common mode signal is 0.5V?
💡 Hint: Break the equation down into its components.
Question 2
Describe how you would analyze a differential amplifier implementing the small signal approximation directly using Kirchhoff's laws.
💡 Hint: Start with a single input and trace current paths through the circuit.
