55.3.2. Motivation for Mixing Configurations

Try these first

1. 1.

   What is the purpose of mixing amplifier configurations?

   Hint

   Think about performance improvement.

2. 2.

   Name one advantage of common collector configuration.

   Hint

   Consider input and output characteristics.

3. 3.

   What does cascading a common collector stage after a common emitter stage achieve?

   • Increases output impedance
   • Decreases output impedance
   • Has no effect

   Hint

   Think about impedance characteristics.

4. 4.

   True or False: The common collector configuration can serve well as a voltage amplifier alone.

   • True
   • False

   Hint

   Reflect on how each configuration is intended to perform.

5. 5.

   Explain the design considerations when choosing to mix CE, CC, and CB configurations for a specific application in an analog system.

   Hint

   Think about the end application's requirements.

6. 6.

   Design a hypothetical amplifier system using CE followed by CC for an audio application. Describe how this impacts the overall circuit performance.

   Hint

   Consider how each stage influences audio performance.
