12.5.5. I-V Characteristics of p-MOSFET

Try these first

1. 1.

   What is the primary carrier responsible for current flow in a p-MOSFET?

   Hint

   Remember the type of material in the channel.

2. 2.

   What happens to the current as the gate-source voltage becomes more negative?

   Hint

   Think about how hole concentration changes.

3. 3.

   What type of semiconductor material is used for the channel in a p-MOSFET?

   • N-type
   • P-type
   • Intrinsic

   Hint

   Think about what the 'p' in p-MOSFET stands for.

4. 4.

   True or False: In a p-MOSFET, the source is typically at a higher potential than the drain.

   • True
   • False

   Hint

   Recall the operation principle.

5. 5.

   Given a p-MOSFET with parameters Vth = -2V, if Vgs = -3V and Vds = -5V, determine if the transistor is in saturation or triode.

   Hint

   Compare Vgs with Vth and analyze Vds.

6. 6.

   Explain how increasing the temperature affects the performance of a p-MOSFET, particularly in terms of mobility and current.

   Hint

   Recall mobility's relationship with temperature in intrinsic semiconductors.
