Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a fixed bias configuration for a common emitter amplifier expecting beta to vary between 100 and 200. Discuss how to prevent distortion.

💡 Hint: Consider how to account for changing beta in your design.

Challenge 2 Hard

Given a BJT's transfer characteristics, predict how changes in the biasing methods will shift the Q point and impact signal amplification.

💡 Hint: Reference the graphs of saturation and active regions.
