Challenge Problems
Push your limits with challenges.
Question 1
If a BJT has a CC of 15V, BE of 0.7V, and RB of 470kΩ, calculate IC and discuss the potential Q-point shift if DC varies by 50%.
💡 Hint: Remember, variations in DC lead to changes in C, which can shift the Q-point.
Question 2
Develop a circuit diagram for a fixed bias BJT, labeling all components and explaining the role of each in maintaining Q-point stability or instability.
💡 Hint: Focus on how each component contributes to or detracts from overall stability.
