Challenge Problems
Push your limits with challenges.
Question 1
Design a Voltage Divider Bias circuit for a BJT with a target Q-point of IC = 5mA and VCE = 7V, given that VCC = 12V. Document your design process and calculations.
💡 Hint: Make sure to recheck the standard component values for precision.
Question 2
Analyze how a significant increase in temperature affects the Q-point in a Fixed Bias circuit. Provide calculations based on an initial β and then with a doubled β.
💡 Hint: Use the relation IC = β * IB to see the dramatic effect on Q-point stability.
