Challenge Problems
Push your limits with challenges.
Question 1
Design a voltage divider bias circuit for an NPN BJT with a target IC of 1mA and VCE of 5V, given VCC=10V. Explain your chosen values for R1 and R2.
💡 Hint: Start by calculating VE and RE based on your stability needs.
Question 2
Calculate the expected shift in Q-point for a fixed bias circuit if the β increases from 100 to 200. Discuss the implications for audio signal distortion.
💡 Hint: Remember how IC is related to the β value.
