70.2. Module-7 Overview

Try these first

1. 1.

   What is the main function of a single-ended amplifier?

   Hint

   Consider what reference point it uses.

2. 2.

   Define a differential amplifier.

   Hint

   Think about its unique input configuration.

3. 3.

   What type of amplifier compares an input signal to ground?

   • Single-Ended Amplifier
   • Differential Amplifier
   • Both

   Hint

   Think about the reference point.

4. 4.

   True or False: A differential amplifier can only amplify signals with a positive difference.

   • True
   • False

   Hint

   Consider the nature of subtraction.

5. 5.

   Given two input signals of 5V and 3V in a differential amplifier with a gain of 10, calculate the output voltage.

   Hint

   Remember the formula involves the difference of inputs multiplied by the gain.

6. 6.

   Analyze a circuit that includes both single-ended and differential amplifiers and discuss the potential noise issues.

   Hint

   Compare how each amplifier addresses noise in their configuration.
