Try these first
- 1.
What is linearization in circuit analysis?
Hint
Remember it helps to deal with small changes.
- 2.
Define transconductance.
Hint
Think about how control input affects output.
- 3.
What does small signal analysis focus on?
- Large variations
- Small variations
- DC signals only
Hint
Focus on changes that matter during linearization.
- 4.
True or False: Transconductance changes with the chosen operating point.
- True
- False
Hint
Remember the impact of Q-point on parameters.
- 5.
A MOSFET has a transconductance of 5 mA/V and operates around a Q-point of 2 mA. If the gate-source voltage increases by 0.5V, calculate the new drain current.
Hint
Use the transconductance formula.
- 6.
What are the consequences in a circuit if the Q-point drifts too far from its designated point?
Hint
Think about the linearity and stability of operations.
