2.6.2. Configurations of Power Amplifiers

Try these first

1. 1.

   What is single-ended signaling?

   Hint

   Think about how a single signal can be represented.

2. 2.

   What does a differential amplifier do?

   Hint

   Focus on the key function of the device.

3. 3.

   What is the main advantage of differential signaling?

   • Simplicity
   • Better noise immunity
   • Lower cost

   Hint

   Remember the role of pairs in communication.

4. 4.

   True or False: Power efficiency is less important than power gain in amplifier applications.

   • True
   • False

   Hint

   Think about resource utilization.

5. 5.

   Assess how a designer can balance the need for high power gain with the requirement for high power efficiency in an audio amplifier.

   Hint

   Consider the role of feedback in managing output.

6. 6.

   Propose a real-world scenario where differential signaling would be preferred despite complexity over single-ended signaling.

   Hint

   Think about environments where clarity is essential.
