70.3. Basic Operation of Single Ended Amplifier

Try these first

1. 1.

   Define a single-ended amplifier.

   Hint

   Think about how it connects to the ground.

2. 2.

   What is the purpose of AC coupling in signal feeding?

   Hint

   How does AC coupling affect DC bias?

3. 3.

   What does a single-ended amplifier process?

   • One input relative to ground
   • Two inputs
   • Feedback only

   Hint

   Focus on the concept of 'single'.

4. 4.

   True or False: Differential amplifiers do not use a common reference.

   • True
   • False

   Hint

   What is the key focus of differential amplification?

5. 5.

   Design a single-ended amplifier configuration based on desired frequency response characteristics.

   Hint

   What components do you need to maintain bias and AC coupling?

6. 6.

   Calculate the gain of a single-ended amplifier given its input and output signal characteristics.

   Hint

   Look for both signal and DC references in your calculations.
