Challenge Problems
Push your limits with advanced challenges
Given a differential amplifier configuration where V_CC = 15V, R_C = 10kΩ, and R_T = 1kΩ, calculate the output DC voltage when the input base voltage is 3V.
💡 Hint: Remember to account for transistor drop and use the Ohm’s law for resistive values.
If you replace the tail resistor R_T in a differential amplifier with an active load, discuss how this would affect differential and common mode gains.
💡 Hint: Consider how active elements influence current flow as opposed to passive resistances.
