Challenge Problems
Push your limits with advanced challenges
A BJT has a β of 100, and you have an input current I_B of 10 µA. Calculate I_C and discuss the implications if the circuit operates outside the optimal biasing region.
💡 Hint: Consider the implications of incorrect biasing on current flow.
Model the impact on both I_C and W_B when V_CB is significantly increased—what happens to the dynamics within the transistor?
💡 Hint: Think about how the physics of semiconductor behavior changes with voltage.
