Challenge Problems
Push your limits with challenges.
Question 1
Consider a BJT amplifier circuit operating with a Q-point set at 5V ahead of a load resistor. If small variations occur within the input voltage, calculate how these affect the output voltage if the beta is 100.
💡 Hint: Reflect on the relationship between input and output under small signal conditions.
Question 2
Explain how you would derive the small signal model for a basic BJT amplifier. What key components would you retain, and how would the relationship between the currents change during linearization?
💡 Hint: Start from the transistor's characteristic equations.
