Challenge Problems
Push your limits with challenges.
Question 1
You have a differential amplifier circuit with a current mirror where the transistors are biased to 2mA. If one branch experiences an increase to 2.1mA due to temperature effects, determine how this affects the mirrored current and the overall performance of the amplifier.
💡 Hint: Think about adjustments in response mechanisms.
Question 2
Given a differential circuit with varied resistor values, calculate the new common mode gain if the resistors change to 100kΩ each and verify its effect on signal rejection.
💡 Hint: Check formulas concerning common mode gain adjustments.
