Challenge Problems
Push your limits with challenges.
Question 1
Consider an amplifier where the measured base voltage (V_B) is 1.2V, collector current (I_C) is 10mA, and collector-emitter voltage (V_CE) is 6V. Discuss whether the Q-point is well set for distortion-free operation. Assume the power supply is 12V.
💡 Hint: Think about the relationship between V_CE and the power supply voltage.
Question 2
Design a circuit that allows for adjusting the Q-point dynamically based on temperature variations to prevent thermal drift in performance. Explain your design.
💡 Hint: Consider components that are temperature sensitive and how they could influence current flow.
