Challenge Problems
Push your limits with challenges.
Question 1
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.
π‘ Hint: Use the Ξ± and Ξ² relationships to guide your biasing decisions.
Question 2
If the collector current in a BJT is given as 10 mA with Ξ² = 100, calculate the base current and determine how changes in V_CB could affect this set-up.
π‘ Hint: Think about how I_B and I_C relate and how voltage influences this relationship.
