Question 1
Given a BJT with β = 100, VBE = 0.7V, and VCC = 12V, design a Fixed Bias circuit and calculate its Q-point. What issues might arise if β changes significantly?
💡 Hint: Pay attention to how β influences base and collector currents.
Question 2
Design a Voltage Divider Bias circuit for a target Q-point of IC = 2mA, VCE = 6V in a 12V supply. Discuss the stability advantages of this setup.
💡 Hint: Use voltage divider principles and remember to consider feedback mechanisms.
