Challenge Problems
Push your limits with advanced challenges
Design a differential amplifier with a current mirror load. Calculate the DC current through each transistor when the supply voltage is 12 V and the resistor is set to 10 kΩ.
💡 Hint: Readjust your calculations based on loading effects.
Given that the common mode gain is significantly lower than differential gain, discuss how this affects signal integrity in real-world applications.
💡 Hint: Think about how noise affects behavior in circuits.
