Practice Questions
Test your understanding with targeted questions
What is the threshold voltage in a MOSFET?
💡 Hint: Think of it as a 'turning on' voltage.
In what region does the MOSFET act like a resistor?
💡 Hint: 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)?
💡 Hint: Think how a gate reacts when not powered.
In which region does a MOSFET primarily exhibit linear behavior?
💡 Hint: Key phrase: TRIode means linear.

Challenge Problems
Push your limits with advanced challenges
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?
💡 Hint: 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.
💡 Hint: Temperature's role can alter performance—think of how it changes mechanics.
