Question 1
What does DC biasing do in a MOSFET amplifier?
- Sets the Q-point
- Prevent overheating
- Boosts AC signals
💡 Hint: Consider why having a 'point' is important for operation.
Question 2
True or False: The AC input signal can create small variations in the gate voltage of a MOSFET.
- True
- False
💡 Hint: Remember that AC signals move up and down rather than being steady.
