62.2.2. Common Source and Common Gate Amplifier

Try these first

1. 1.

   What is the primary purpose of a common source amplifier?

   Hint

   It corresponds to a similar configuration in BJTs.

2. 2.

   What do we call a configuration that allows current conveyance from a source to a drain?

   Hint

   Think about its role in current transfer.

3. 3.

   What does a common source amplifier primarily do?

   • It conveys current
   • It amplifies voltage
   • It does not amplify

   Hint

   Recall its function in signal processing.

4. 4.

   True or False: Common gate amplifiers transfer current without amplification.

   • True
   • False

   Hint

   Think about the role of the gate in this configuration.

5. 5.

   Design a cascode amplifier that allows for a maximum output voltage swing. Discuss the implications of biasing and component selection.

   Hint

   Consider voltage ratings and operational conditions for both transistors.

6. 6.

   Evaluate the bandwidth limitations of a common source amplifier in a cascode configuration. How could feedback be implemented to combat these limitations?

   Hint

   Reflect on how feedback affects both gain and stability in amplifiers.
