Challenge Problems
Push your limits with challenges.
Question 1
Calculate the effective common mode gain when you have a common mode voltage of 1V resulting in 3V at the output. If a differential voltage of 2V is applied, what will be the output voltage?
💡 Hint: Remember to break down the problem step by step.
Question 2
Design a differential amplifier circuit with specific resistor values that allows for a maximum input common mode voltage of 5V, where both transistors stay in their active region.
💡 Hint: Focus on the specifications provided and balance both active regions.
