Question 1

What does the parameter W represent in a MOSFET's current equation?

  • Length of the channel
  • Width of the channel
  • Voltage to the gate

πŸ’‘ Hint: Think of how widening a pipe helps carry more water.

Question 2

True or False: Increasing the length (L) of a MOSFET will increase the Ids.

  • True
  • False

πŸ’‘ Hint: Consider how length affects travel time on a road.

Challenge Problems

Push your limits with challenges.

Question 1

A circuit designer is developing a high-speed amplifier with a required Ids of 10 mA. If the designer increases W by 50% without changing L, how does that impact Ids?

πŸ’‘ Hint: Look at the relationship between W and Ids.

Question 2

You're tasked with ensuring the MOSFET operates efficiently just below pinch-off while maximizing Ids. How would you adjust the parameters?

πŸ’‘ Hint: Consider how each parameter's adjustment influences the conductivity.
