70.3.2. DC Part and Signal Part

Try these first

1. 1.

   Define a Single-Ended Amplifier.

   Hint

   Think about the signal and ground reference.

2. 2.

   What does a Differential Amplifier do?

   Hint

   Focus on 'difference' between inputs.

3. 3.

   What is a single-ended amplifier?

   • An amplifier with two inputs
   • An amplifier with one input referencing a ground
   • An amplifier with no inputs

   Hint

   Focus on the input configuration.

4. 4.

   True or False: A differential amplifier processes the average of two signals.

   • True
   • False

   Hint

   Consider what the amplifier is designed to do.

5. 5.

   Design a simple circuit for a differential amplifier using two separate input voltages, V1 and V2. Describe how the circuit would operate in the presence of common noise.

   Hint

   Think about how noise affects both V1 and V2.

6. 6.

   Evaluate the impacts of common-mode rejection in an environment with high EMI (Electromagnetic Interference). Describe how a differential amplifier would perform versus a single-ended amplifier.

   Hint

   Consider the amplification effects of both configurations in noisy conditions.
