Question 1.
What does the Q-point represent in a BJT circuit?
Show hintHide hint
Consider what operating point means in the context of circuits.
Question 2.
Define transconductance (gm).
Show hintHide hint
Think about the relationship between input voltage and output current.
3Question 3.
What is the purpose of the small signal model?
- To analyze only linear circuits
- To linearize non-linear devices for easier analysis
- To calculate power loss
Show hintHide hint
Think about what simplifications are needed for circuit analysis.
4Question 4.
True or False: The Q-point changes dynamically with signal processing.
- True
- False
Show hintHide hint
Consider if the biasing affects signal processing.
Question 5.
Given a BJT with a collector current (Ic) of 1 mA and Early voltage (VA) of 50V, calculate the output conductance (go).
Show hintHide hint
Be sure to use the correct units in your calculation.
Question 6.
A BJT has a transconductance of 5 mA/V and is connected to a load of 2 kΩ. What is the expected voltage gain?
Show hintHide hint
Remember the relationship for voltage gain calculation.
