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.
