Challenge Problems
Push your limits with challenges.
Question 1
Design a fixed bias circuit for a BJT with a desired collector current of 5 mA, given VCC = 12V and a target VCE = 2V. Determine RB and RC values assuming β = 100.
💡 Hint: Focus on manipulating VCE to find RC and then IB for RB.
Question 2
Suppose a fixed bias circuit experiences a temperature increase causing β to rise by 50%. Discuss how this impacts IC and VCE, providing imaginary numbers.
💡 Hint: Visualize how thermal characteristics influence current flow and lead to undesired states.
