Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
