5.3. Types of MOSFET Amplifier Configurations

Try these first

1. 1.

   What is the main characteristic of a Common Source amplifier?

   Hint

   Think about the amplification factor.

2. 2.

   Does a Common Drain amplifier provide unity gain?

   Hint

   Recall the purpose of a buffer.

3. 3.

   Which amplifier configuration provides the highest gain?

   • Common Source
   • Common Drain
   • Common Gate

   Hint

   Think about which configuration amplifies signals most effectively.

4. 4.

   True or False: A Common Drain amplifier has a phase shift in the output signal.

   • True
   • False

   Hint

   Recall the nature of a buffer amplifier.

5. 5.

   Design a multi-stage amplifier using a Common Source followed by a Common Drain. Describe the characteristics you expect from each stage.

   Hint

   Focus on how each configuration affects the signals as they pass through.

6. 6.

   What challenges might arise when using a Common Gate amplifier in a low-frequency application, and how could you mitigate them?

   Hint

   Consider the trade-offs between frequency response and impedance.
