12.6. Conclusion

Try these first

1. 1.

   What do p-MOSFETs use as charge carriers?

   Hint

   Think about the type of semiconductor material.

2. 2.

   Describe how p-MOSFETs are biased for operation.

   Hint

   Focus on the potential differences.

3. 3.

   What type of charge carriers do p-MOSFETs use?

   • Electrons
   • Holes
   • Neutrons

   Hint

   Recall the semiconductor material type.

4. 4.

   True or False: In a p-MOSFET, the gate must be at a higher potential than the source for it to operate.

   • True
   • False

   Hint

   Think about how biasing affects transistor behavior.

5. 5.

   A p-MOSFET has a threshold voltage of -1V. If a gate voltage of -3V and a drain-source voltage of -4V is applied, determine if the device is operating in saturation and calculate the drain current.

   Hint

   Pay attention to voltage polarities and compare them for current calculations.

6. 6.

   Discuss the effects on a p-MOSFET's I-V characteristics when body and source are tightly coupled versus loosely connected.

   Hint

   Consider impacts on junctions in semiconductor devices.
