6 sample questions

Question 1.
What is the quiescent point (Q-point) in aMOSFET circuit?
Show hintHide hint
Think of where the transistor operates without any signal input.
Question 2.
Why are MOSFETs considered non-linear?
Show hintHide hint
Consider the transfer characteristic graph shape.
3Question 3.
What is the purpose of using a Q-point in MOSFET circuits?
- To find current gain
- To stabilize the operating point
- To maximize output distortion
Show hintHide hint
Think about where you want a transistor to operate.
4Question 4.
MOSFET transfer characteristics are typically linear.
- True
- False
Show hintHide hint
Reflect on transfer characteristic graphs.
Question 5.
A MOSFET has a transconductance of 6 mA/V², and the threshold voltage is 2V. If V_gs is increased from 4V to 5V while maintaining a load resistor of 1kΩ, calculate the output voltage change across the load.
Show hintHide hint
Make sure to compute the output voltage for both states to find the difference.
Question 6.
Design a small-signal model for a circuit involving two MOSFETs in a differential amplifier configuration. Consider their individual Q-points and account for their interaction.
Show hintHide hint
Focus on understanding how each MOSFET impacts the circuit while linearizing them about their operating points.
