12.5.4. Biasing of p-MOSFET

Try these first

1. 1.

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

   Hint

   Remember the 'P' in p-MOSFET stands for?

2. 2.

   What is the function of the gate in a p-MOSFET?

   Hint

   Think about how we apply voltage to it.

3. 3.

   What is the primary function of the gate in a p-MOSFET?

   • To provide a voltage source
   • To control current flow
   • To serve as a drain

   Hint

   Think about what regulates the movement of charge carriers.

4. 4.

   True or False: In a p-MOSFET, electrons flow from the source to the drain.

   • True
   • False

   Hint

   Consider the nature of charge carriers in p-MOSFETs.

5. 5.

   Explain how you would design a circuit using both n-MOSFETs and p-MOSFETs to create a complementary push-pull inverter.

   Hint

   Think of how both devices complement each other in operation.

6. 6.

   Describe the operational conditions where a p-MOSFET reaches its 'pinch-off' point, and explain what implications this has on current flow.

   Hint

   What happens to channels when the voltage gets too high?
