5.12. Summary of Key Concepts

Try these first

1. 1.

   What is the output phase shift in a Common Source amplifier?

   Hint

   Think about how the output relates to the input.

2. 2.

   Which configuration acts as a buffer?

   Hint

   This configuration has unity gain.

3. 3.

   In a Common Source amplifier, what is the phase relationship between input and output?

   • In phase
   • Out of phase
   • No phase relationship

   Hint

   Consider what happens to the voltage levels.

4. 4.

   True or False: Common Drain amplifiers provide high gain.

   • True
   • False

   Hint

   Think about the buffer's functionality.

5. 5.

   Design a MOSFET amplifier circuit using a Common Source configuration, listing its components and calculating the expected output voltage for a given input signal.

   Hint

   Remember to check the values of gm for your specific MOSFET.

6. 6.

   Discuss the implications of operating a MOSFET amplifier outside the saturation region. What are potential distortions that may occur?

   Hint

   Consider how linear performance aids in amplification.
