4.2. Types of MOSFETs

Try these first

1. 1.

   What is the main difference between Enhancement and Depletion Mode MOSFETs?

   Hint

   Think about when the channel exists.

2. 2.

   Which type of MOSFET is typically preferred, n-channel or p-channel?

   Hint

   Consider which conducts better.

3. 3.

   What is true about Enhancement Mode MOSFETs?

   • They require voltage to activate the channel.
   • They have a default channel.
   • They operate at higher currents than D-MOSFETs.

   Hint

   Consider which type has to be energized to work.

4. 4.

   True or False: n-channel MOSFETs are less efficient than p-channel MOSFETs.

   • True
   • False

   Hint

   Think about carrier types and performance.

5. 5.

   A circuit requires a consistent current flow without the need for additional voltage. Which type of MOSFET would be more appropriate and why?

   Hint

   Consider which MOSFET is always ready to conduct.

6. 6.

   If you were to design a voltage-controlled switch using E-MOSFETs, explain how you would set it up.

   Hint

   Think about the function of voltage in activating the channel.
