Challenge Problems
Push your limits with challenges.
Question 1
Given a BJT operating at a collector current of 10 mA with a transconductance of 10 mS, calculate the base-emitter voltage required to maintain this current if the input base current is 0.1 mA.
💡 Hint: Relate the transconductance to input and output relations.
Question 2
In a circuit, if r_π is given as 1.2 kΩ, and collector current I_c is 5 mA, what would be the expected input voltage to base assuming a small signal?
💡 Hint: Recall the relationships between input current, base-emitter resistance, and how they affect voltage.
