17.3. Circuit of Consideration

Try these first

1. 1.

   What does MOSFET stand for?

   Hint

   Think about the structure of the transistor.

2. 2.

   Define transconductance.

   Hint

   Consider the current and voltage relationship.

3. 3.

   What is the primary function of a MOSFET in a circuit?

   • Amplification
   • Switching
   • Both Amplification and Switching

   Hint

   Recall the roles MOSFETs play in electronics.

4. 4.

   True or False: The output voltage in a MOSFET circuit is always higher than the input voltage.

   • True
   • False

   Hint

   Consider the relationships between input and output.

5. 5.

   Design a simple NMOS amplifier circuit, specifying all components and their values to achieve a desired gain of 10.

   Hint

   Use your knowledge of the gain formula.

6. 6.

   Explain the operating point and how it shifts when the load resistance is altered from 4kΩ to 1kΩ.

   Hint

   Consider what happens to current and voltage as resistance changes.
