4 cards from this lesson. Good the night before a test.
Try these first
- 1.
What is V_GS?
Hint
Think about the voltages at the gate and source.
- 2.
Why is V_th important?
Hint
Relate it to how MOSFETs function.
- 3.
What condition must V_D satisfy to keep the MOSFET in saturation?
- V_D < V_GS - V_th
- V_D = V_th
- V_D > V_GS - V_th
Hint
Think about how saturation works.
- 4.
True or False: The gate current in a common source amplifier is significant.
- True
- False
Hint
Consider the properties of the MOSFET.
- 5.
Design a common source amplifier that requires a target I_DS of 2A. Determine suitable values for V_GS and V_th using K = 0.4 A/V^2.
Hint
What rearrangements can you make to isolate V_th?
- 6.
Discuss the effects on output signal if V_GS is set too low, considering saturation conditions.
Hint
How does low V_GS affect the amplifier's function?
