Challenge Problems
Push your limits with challenges.
Question 1
An amplifier designed with a BJT has a Q-point set at IC = 1 mA with beta = 100. If the temperature increases and beta rises to 150, discuss the potential impacts on the amplifier's performance.
💡 Hint: Analyze how changes in collector current affect the overall amplifier function.
Question 2
Given that a BJT's collector current is influenced by the leakage current, outline how you would design a system that minimizes distortion induced by this factor. Discuss biasing techniques that could help.
💡 Hint: Consider how different biasing techniques control collector current against leakage.
