Challenge Problems
Push your limits with challenges.
Question 1
Given a differential amplifier configuration with current mirrors, derive the expression for differential mode gain in terms of transconductance and load resistance.
💡 Hint: Recall how transconductance interacts with load resistance.
Question 2
A differential amplifier uses a current mirror to replace a tail resistor providing a reference current. If the reference current is 2 mA, calculate the tail current for identical transistors.
💡 Hint: Focus on the properties of current mirrors providing equal current to their branches.
