Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
