Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is the collector current for a fixed bias amplifier when the base current is 20 µA and beta is 100?
💡 Hint: Use the formula I_C = β * I_B.
Question 2
Easy
Define a fixed bias configuration.
💡 Hint: Think about how the bias point is determined.

Challenge Problems
Push your limits with challenges.
Question 1
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.
Question 2
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.
