Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a circuit that utilizes BJTs to achieve a specific amplification gain. Explain how you would determine the necessary biasing conditions and the impact of base width reduction at higher voltages.

💡 Hint: Use the α and β relationships to guide your biasing decisions.

Challenge 2 Hard

If the collector current in a BJT is given as 10 mA with β = 100, calculate the base current and determine how changes in V_CB could affect this set-up.

💡 Hint: Think about how I_B and I_C relate and how voltage influences this relationship.
