Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a BJT with a collector current of 4 mA and a transconductance of 1.5 mS, calculate the change in collector current for a change of 0.1 V in VBE.

💡 Hint: Use the transconductance formula to find the change.

Challenge 2 Hard

Analyze how varying the base-emitter voltage affects the current gain of a BJT amplifier. Explain how the operating point affects your analysis.

💡 Hint: Consider how the gain relates to voltage changes.
