Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
