Challenge Problems
Push your limits with challenges.
Question 1
You have a differential amplifier with a differential input of 0.1 V and common mode input of 1 V. If the differential gain is 2000, what will be the output voltage?
💡 Hint: Focus on how the differential gain is applied to the input difference.
Question 2
Calculate the impact of Early voltage on the output current of a current mirror if the Early voltage is 50V and Vce for the output transistor is 1V.
💡 Hint: Think about how the current mirror effectiveness correlates with Early voltage.
