Challenge Problems
Push your limits with advanced challenges
Given a BJT cascode amplifier with a supply voltage of 15 V, β for the first transistor is 150, and a load resistance of 2 kΩ, calculate its output voltage if the input voltage is 0.5 V and β for the second transistor is 180.
💡 Hint: Start by finding I_C for both transistors first.
Discuss implications of increasing the Early voltage in a cascode amplifier—how would it alter performance metrics?
💡 Hint: Think about how output behavior changes with variations in supply voltage.
