Challenge Problems

Push your limits with challenges.

Question 1

Design a self-bias circuit that maintains a collector current of 2mA regardless of changes in beta, considering a supply voltage of 12V.

πŸ’‘ Hint: Use the relationship between collector current, base current, and resistances.

Question 2

If a fixed bias circuit experiences an increase in beta causing saturation, outline redesign steps to restore stability.

πŸ’‘ Hint: Consider how you can manage the primary current paths in your circuit.
