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.
