Challenge Problems
Push your limits with challenges.
Question 1
Consider a fixed bias configuration with varying beta due to temperature changes. What happens to the collector current if beta drops from 100 to 80 while V_CC is constant?
💡 Hint: Analyze the formula I_C = β * I_B. How does a lower beta impact I_C?
Question 2
Design a self-bias configuration to achieve a specific gain. If you want a collector current of 2 mA with a β of 100, how would you choose R_B and R_E?
💡 Hint: Think about how base and emitter resistors relate to biasing and gain.
