4 cards from this section. Quick, good the night before a test.
What is the threshold voltage in a MOSFET?
Think of it as a 'turning on' voltage.
In what region does the MOSFET act like a resistor?
Remember, TRI - the start of TRIode means it behaves like a resistor!
What happens when the gate-source voltage (VSG) is less than the threshold voltage (Vth)?
Think how a gate reacts when not powered.
In which region does a MOSFET primarily exhibit linear behavior?
Key phrase: TRIode means linear.
Given a MOSFET with a Y parameter and a threshold voltage, calculate the threshold current when VGS is increased to a specific level. What fraction of increase does this reflect in terms of resistance across the channel?
Consider how increasing voltage influences resistance.
If a MOSFET is subjected to a constant channel length modulation effect, describe how changing ambient temperature can affect the stability of the output current.
Temperature's role can alter performance—think of how it changes mechanics.
