55.4. Performance Summarization

Try these first

1. 1.

   What is the primary function of a Common Emitter amplifier?

   Hint

   Think about where you might need a strong amplification.

2. 2.

   What does a Common Collector amplifier primarily do?

   Hint

   Consider its use as a mediator between stages.

3. 3.

   What is the primary advantage of a Common Collector amplifier?

   • High voltage gain
   • High input impedance
   • High current gain

   Hint

   Remember what type of applications need this characteristic.

4. 4.

   True or False: The Common Emitter configuration is suitable for both voltage and current amplification.

   • True
   • False

   Hint

   Think about CE's role in different contexts.

5. 5.

   Design a multi-stage amplifier using CE, CC, and CB that optimally combines their strengths. What key parameters will ensure its success in a specific application?

   Hint

   Identify each transistor's role and how they connect.

6. 6.

   Explain the potential issues if a Common Base configuration is directly connected to a load without proper sourcing from a Common Emitter stage.

   Hint

   Focus on the relationship between input and output characteristics.
