Challenge Problems
Push your limits with advanced challenges
If a BJT circuit has a quiescent current of 1mA and the base-emitter voltage is 0.7V, calculate the transconductance and the base-emitter resistance.
💡 Hint: Recall how to derive these values from the definitions.
Discuss how changing the Q-point affects the linearity of the output. Include graphs to illustrate your answer.
💡 Hint: Visualize different Q-points on the I-V characteristics to see variations.
