Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
