4 cards from this section. Quick, good the night before a test.
What is V_GS?
Think about the voltages at the gate and source.
Why is V_th important?
Relate it to how MOSFETs function.
What condition must V_D satisfy to keep the MOSFET in saturation?
Think about how saturation works.
True or False: The gate current in a common source amplifier is significant.
Consider the properties of the MOSFET.
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.
What rearrangements can you make to isolate V_th?
Discuss the effects on output signal if V_GS is set too low, considering saturation conditions.
How does low V_GS affect the amplifier's function?
