Challenge Problems
Push your limits with advanced challenges
Given a CE amplifier with V_CC = 10V, I_C = 1.5mA, and I_B = 7.5µA, calculate the total power dissipation. Discuss what this implies for the circuit design.
💡 Hint: Focus on converting all currents into the same measurement before calculating.
Analyze how increasing the collector current to 3mA while keeping the same voltage impacts the efficiency and what adjustments could be made in the design.
💡 Hint: Consider engineering adjustments—how can currents and resistances interrelate to maintain performance?
