Question 1.
What is the base to emitter resistance in a BJT?
Show hintHide hint
Think about where the base current is going.
Question 2.
Define transconductance.
Show hintHide hint
How does this relate to current and voltage?
3Question 3.
What is the small signal model primarily used for?
- To calculate DC current
- To linearize the non-linear circuit
- To design digital circuits
Show hintHide hint
Think about why we need to simplify complex behaviors.
4Question 4.
True or False: Transconductance is independent of the Q-point.
- True
- False
Show hintHide hint
Remember how parameters may change with operating conditions.
Question 5.
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.
Show hintHide hint
Recall how to derive these values from the definitions.
Question 6.
Discuss how changing the Q-point affects the linearity of the output. Include graphs to illustrate your answer.
Show hintHide hint
Visualize different Q-points on the I-V characteristics to see variations.
