Challenge Problems
Push your limits with challenges.
Question 1
Design a BJT Fixed Bias circuit to achieve a Q-point of IC = 3mA and VCE = 7V while considering component tolerances and variations. Discuss how you would ensure stability against parameter changes.
💡 Hint: Take into account the maximum and minimum values for each resistor based on standard tolerances.
Question 2
Analyze the implications of replacing a transistor in a Voltage Divider Bias circuit versus a Fixed Bias circuit. Describe how the Q-point might shift in each case.
💡 Hint: Reflect on the role of feedback in Voltage Divider Bias compared to the Fixed Bias approach.
