55.5. Mixing Configurations

Try these first

1. 1.

   What is the main purpose of mixing configurations?

   Hint

   Think about how different components work together.

2. 2.

   Name one benefit of the common emitter configuration.

   Hint

   Remember the role of voltage in amplifiers.

3. 3.

   What is the primary benefit of using a common collector configuration?

   • High input impedance
   • Low output impedance
   • High voltage gain

   Hint

   Focus on what you want to match with this configuration.

4. 4.

   True or False: A common base configuration is typically used for voltage amplifiers.

   • True
   • False

   Hint

   Consider the input characteristics of different configurations.

5. 5.

   Design a basic amplifier circuit that uses both common emitter and common collector configurations. What performance enhancements can you expect?

   Hint

   Think about how the CC configuration influences CE performance.

6. 6.

   Explain how cascading a common base after a common emitter can improve performance in high-frequency applications.

   Hint

   Reflect on the properties of each configuration in high-frequency scenarios.
