Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a Fixed Bias Circuit for a hypothetical BJT with VCC = 10V, β = 150, and VBE = 0.7V. Determine the values of RB and RC to achieve a collector current of 5mA.

💡 Hint: Balance the current calculations for the design aspects.

Challenge 2 Hard

Evaluate how replacing the BJT in the Fixed Bias Circuit with one that has a β that is 50% lower would affect the Q-point.

💡 Hint: Consider the role of β in current amplification.
