Challenge Problems
Push your limits with challenges.
Question 1
Design a collector feedback bias circuit for a BJT. Given VCC = 15V and target IC of 5 mA, determine RB for stable operation assuming β = 100.
💡 Hint: Consider the impact of changing β on your calculated RB.
Question 2
If the temperature rises causing β to double, explain stepwise how this impacts IB, IC, and the overall Q-point without altering VCC.
💡 Hint: Think about the feedback mechanism when IC begins to rise.
