Try these first

1. 1.

   What is a composite transistor?

   Hint

   Think about how multiple elements can create a simplified unit.

2. 2.

   Define Common Collector Configuration.

   Hint

   Consider its function in amplifier design.

3. 3.

   What configuration provides a voltage gain of approximately 1?

   • Common Collector
   • Common Emitter
   • Common Source

   Hint

   Think about the role of the collector in this setup.

4. 4.

   True or False: The Darlington pair configuration enhances input resistance significantly.

   • True
   • False

   Hint

   Recall the purpose of this configuration.

5. 5.

   Design a composite transistor circuit consisting of a CC stage followed by a CE stage. Calculate the overall voltage gain given the gains of its components.

   Hint

   Remember to align your gains correctly.

6. 6.

   Discuss the limitations of using Darlington pairs in high-frequency applications.

   Hint

   Consider how each additional component affects speed.
