55.1.5. Multi – Transistor Amplifiers: Operation and Analysis (Part A)

Try these first

1. 1.

   What is a common emitter amplifier used for?

   Hint

   Think about its gain characteristics.

2. 2.

   What does a common collector amplifier primarily do?

   Hint

   Recall its input and output characteristics.

3. 3.

   What is the primary function of a common collector amplifier?

   • To amplify voltage
   • To act as a buffer
   • To increase output resistance

   Hint

   Think about the role it plays in a circuit.

4. 4.

   True or False: The common emitter configuration is suitable for current amplification only.

   • True
   • False

   Hint

   Recall the functions it serves within a circuit.

5. 5.

   Design a multi-stage amplifier circuit using CE, CC, and CB configurations. Explain the expected performance metrics.

   Hint

   Focus on how each amplifier aids in achieving specific performance goals.

6. 6.

   Evaluate a scenario where using a common base amplifier might be favored over common emitter or collector. Discuss its advantages.

   Hint

   Think about the specific advantages of lower impedance in high frequency.
