74.4. Variants of Differential Amplifier

Try these first

1. 1.

   What is the primary function of a differential amplifier?

   Hint

   Think about what differential means.

2. 2.

   Name one application where a fully differential amplifier would be used.

   Hint

   Consider scenarios where noise is a concern.

3. 3.

   What is the main advantage of a fully differential amplifier over a single-ended amplifier?

   • Easier to implement
   • Better noise suppression
   • Lower cost

   Hint

   Think about signal quality.

4. 4.

   True or False: A differential amplifier amplifies both differential and common mode signals equally.

   • True
   • False

   Hint

   What should happen to the common signals?

5. 5.

   Design a circuit using various amplifier types to achieve optimal noise suppression in a manufacturing facility exposed to electrical interference.

   Hint

   Consider how each type affects incoming signals.

6. 6.

   Evaluate the performance of a fully differential amplifier versus a single-ended amplifier in a noisy environment, specifying key metrics.

   Hint

   Focus on the implications of common mode rejection.
