Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a BJT Fixed Bias circuit for a voltage of VCC = 12V and a desired Q-point of IC = 5mA. How would you choose your resistor values, considering βDC = 100?

💡 Hint: Start with isolating the key parameters of your desired circuit.

Challenge 2 Hard

Illustrate the effect of temperature changes on the Q-point of a BJT Voltage Divider circuit and explain how the circuit design mitigates these changes.

💡 Hint: Consider the feedback roles of the base and emitter resistors.
