10.2. Lecture - 10

Try these first

1. 1.

   What are the three main components of a MOSFET?

   Hint

   Think about the 'M' in MOSFET.

2. 2.

   What happens to majority carriers in the channel when a voltage is applied?

   Hint

   Consider what happens to holes in a p-type material.

3. 3.

   What does MOSFET stand for?

   • Metal-Oxide-Semiconductor Field-Effect Transistor
   • Metal-Oxide-Semiconductor Function Effect Transistor
   • Metal-Opposite-Semiconductor Field-Effect Transistor

   Hint

   Remember the components of the name.

4. 4.

   True or False: The channel of an n-MOSFET is originally n-type before voltage is applied.

   • True
   • False

   Hint

   Think about what happens when voltage is applied.

5. 5.

   Design an analog circuit using both n-MOS and p-MOS transistors to exhibit complementary behavior. What considerations will you need to make regarding their biasing?

   Hint

   How do the supply voltages need to accommodate both types of transistors?

6. 6.

   Given an n-MOSFET I-V graph, analyze and explain how the current changes as the gate voltage increases past Vth.

   Hint

   Look for trends in the graph that indicate increasing conductance.
