10.7.1. Application of I-V Characteristic Equation

Try these first

1. 1.

   What are the three components of a MOSFET?

   Hint

   Think about you heard about the term 'MOS'.

2. 2.

   What is the purpose of the oxide layer in a MOSFET?

   Hint

   Consider the conductive function of the other parts.

3. 3.

   What is the relationship between V_GS and the current in an n-MOSFET?

   • Directly proportional
   • Inversely proportional
   • Unrelated

   Hint

   Think about how applying a gate voltage affects current flow.

4. 4.

   True or False? The saturation region of a MOSFET allows for continuous current flow.

   • True
   • False

   Hint

   What happens during saturation in other electronic components?

5. 5.

   A MOSFET has V_GS = 3V and V_th = 1V. If V_DS increases to 0.5V, what happens to the current, and why?

   Hint

   What region is the MOSFET operating in?

6. 6.

   In a circuit, how might the I-V characteristic graph change if the size of a MOSFET is increased?

   Hint

   Consider the geometry's effect on electrical characteristics.
