Challenge Problems
Push your limits with challenges.
Question 1
Given a circuit with transistor Q1 having a transconductance of 15 mS and an output resistance of 20 kΩ, calculate the voltage gain. Then analyze how this would change if the load capacitance increased.
💡 Hint: Draw the small-signal model to visualize changes in the circuit.
Question 2
Consider an amplifier where the early voltage is given as 100V, and the collector current is set to 2 mA. Calculate the increased output resistance and its effects on amplification when adjusting the collector-emitter voltage.
💡 Hint: Relate increased resistance to the operational limits of gain.
