45.4.1. Common Collector Stage with Source Resistance

Try these first

1. 1.

   What is the voltage gain of a common collector amplifier?

   Hint

   Think about the definition of a buffer amplifier.

2. 2.

   Define source resistance.

   Hint

   What connects to the input of an amplifier?

3. 3.

   What is the primary function of a common collector amplifier?

   • It provides amplification.
   • It provides buffering.
   • It provides filtering.

   Hint

   Consider what happens to signal levels in an amplifier.

4. 4.

   True or False: The presence of source resistance does not affect the voltage gain of a common collector amplifier.

   • True
   • False

   Hint

   Remember how source resistance plays a role in voltage levels.

5. 5.

   Calculate the voltage gain for a common collector amplifier with an input resistance of 1MΩ and a source resistance of 100kΩ. What assumptions are you making?

   Hint

   Pay attention to the voltage division concept.

6. 6.

   If R_s varies in value, explain how that would impact signal integrity in a common collector setup. Discuss specific values and scenarios.

   Hint

   Think about how voltage dividers work and their implications.
