Challenge Problems
Push your limits with challenges.
Question 1
Design a circuit that incorporates a BJT and specify how you would find and justify your Q-point. Include calculations for your expected input and output voltages.
💡 Hint: Consider the relationship between input currents and output currents, especially focusing on finding the bias point within the linear range.
Question 2
Given a linearized BJT circuit model, if the input voltage increases by 0.05V and the gain is measured at 50, calculate the expected output voltage change.
💡 Hint: Use the relationship between input and output to express the changes simply.
