Challenge Problems

Push your limits with challenges.

Question 1

Design a common emitter amplifier with an active load. Calculate the expected voltage gain if the resistor value is 4k ohms and the quiescent current is 10 mA.

💡 Hint: Use the relationship between current, resistance, and gain in your calculations.

Question 2

You have a common source amplifier experiencing thermal runaway due to supply voltage increases. Propose a solution that includes active load analysis.

💡 Hint: Think about how active loads can manage current variations better than passive ones.
