Show hintHide hint
Think about the benefits of linear modeling in circuit analysis.
3Question 3.
What does transconductance represent in a BJT?
- Resistance to current
- Change in collector current per change in base-emitter voltage
- Static current behavior
Show hintHide hint
Think about how input affects output in BJTs.
4Question 4.
True or False: The output conductance defines a constant relationship between collector current and collector-emitter voltage.
- True
- False
Show hintHide hint
Reflect on how varying conditions may influence circuit behaviors.
Question 5.
A BJT circuit has a collector current of 5mA and a β of 250. How would you expect the output conductance to behave if the collector-emitter voltage is increased? Provide the explanation as well!
Show hintHide hint
Reflect on how voltage can alter current pathways in BJTs.
Question 6.
Given a BJT circuit with defined values, illustrate how you would derive the small signal voltage gain formula considering g_m, R_C, and load resistances in your approach.
Show hintHide hint
Use relationships derived in class and apply them to the new components.
