12.5.3. Comparison of p-MOSFET and n-MOSFET

Try these first

1. 1.

   What type of channel does a p-MOSFET use?

   Hint

   Remember the type of charge carriers used.

2. 2.

   Which voltage is needed to turn on a p-MOSFET?

   Hint

   Consider how you would bias the device.

3. 3.

   What is the operational voltage required for a p-MOSFET to create a channel?

   • Positive
   • Negative
   • Zero

   Hint

   Think about the nature of charge carriers.

4. 4.

   In an n-MOSFET, which direction does the current flow?

   • True
   • False

   Hint

   Recall the definition of n-MOSFET operations.

5. 5.

   Design a circuit that integrates both p-MOSFET and n-MOSFET to create a simple amplifier. Calculate appropriate biasing for both devices.

   Hint

   Refer back to the principles of biasing discussed.

6. 6.

   Evaluate the impact of temperature changes on the operation of both p-MOSFET and n-MOSFET. What will happen if the threshold voltage shifts?

   Hint

   Consider how temperature affects semiconductor behavior.
