44.1.1. Output Resistance

Try these first

1. 1.

   What does output resistance indicate in an amplifier circuit?

   Hint

   Think about what happens to voltage when you connect a resistor.

2. 2.

   What is the primary advantage of using a common collector amplifier?

   Hint

   Recall what the acronym for the configuration is.

3. 3.

   What is the output resistance of a common collector amplifier generally considered to be?

   • High
   • Low
   • Variable

   Hint

   Think about the characteristics that make amplifiers effective.

4. 4.

   True or False: A common collector amplifier has unity gain.

   • True
   • False

   Hint

   Recall the definition of a voltage buffer.

5. 5.

   Design a common collector amplifier circuit for specific input and output specifications. Calculate the expected output resistance based on your circuit design.

   Hint

   Consider using the real transistor parameters provided in the specifications.

6. 6.

   Evaluate two common collector amplifier designs: one with simple biasing and one with complex load patterns. Discuss implications for output resistance and performance.

   Hint

   Think about how different configurations can change output performance.
