55.4.2. Basic Three Configurations

Try these first

1. 1.

   Describe the role of the Common Emitter configuration in amplification.

   Hint

   Think about its applications in voltage amplifiers.

2. 2.

   What does a Common Collector configuration do?

   Hint

   Recall how it helps in impedance matching.

3. 3.

   What is the primary advantage of the Common Emitter configuration?

   • Low output resistance
   • High voltage gain
   • Low input resistance

   Hint

   Think of its role in voltage amplification.

4. 4.

   True or False: Common Collector configuration provides a significant voltage gain.

   • True
   • False

   Hint

   Consider its primary function as a buffer.

5. 5.

   Design an amplifier circuit that requires both high voltage gain and impedance matching. Indicate how you would use CE and CC in your design.

   Hint

   Focus on how each stage interacts in terms of impedance.

6. 6.

   Critique the use of a Common Base stage in a current amplification application. What considerations must be taken regarding input and output characteristics?

   Hint

   Think about the implications of input and output impedance in the context of maximum transfer.
