74.4.1. Fully Differential Amplifier

Try these first

1. 1.

   What is the main function of a differential amplifier?

   Hint

   Think about the noise and the information we want to keep.

2. 2.

   Define common mode signals.

   Hint

   These signals are unwanted and often considered noise.

3. 3.

   What is the main goal of a fully differential amplifier?

   • To amplify common mode signals
   • To amplify the difference between two signals
   • To eliminate all signals

   Hint

   Focus on the 'difference' aspect.

4. 4.

   True or False: Common mode signals are the same as differential signals.

   • True
   • False

   Hint

   Think about how they operate.

5. 5.

   Explain how a fully differential amplifier can improve a communication system's performance in detail.

   Hint

   Consider the steps involved in signal transmission.

6. 6.

   Design a simple differential amplifier circuit and describe its expected performance metrics.

   Hint

   Recall the basic structure of a differential amplifier.
