Challenge Problems
Push your limits with challenges.
Question 1
Given a BJT with a beta of 150, design a voltage divider bias with V_CC of 10V, aiming for a Q-point of I_C=3 mA and V_E=1.5V. Calculate R1, R2, and R_E.
💡 Hint: Remember the relationships in Ohm's law for resistance calculations.
Question 2
Analyze what happens to the amplifier’s performance if the voltage divider resistors R1 and R2 are significantly miscalculated.
💡 Hint: Think about what happens when the operating point shifts out of the active region.
