2.2.2. Gain Analysis - Differential and Common Mode

Try these first

1. 1.

   Define single-ended signaling.

   Hint

   Think about how many wires are used and what one of them does.

2. 2.

   What is the primary benefit of differential signaling?

   Hint

   Consider how signals are transmitted.

3. 3.

   What is single-ended signaling?

   • A method using two wires
   • A method using one wire
   • A method with no wires

   Hint

   Remember how many wires are used in this signaling type.

4. 4.

   True or False: Differential signaling helps reduce noise.

   • True
   • False

   Hint

   Think about its function compared to single-ended signaling.

5. 5.

   A sensor measures small temperature variations. Design a differential amplifier considering differential and common mode gain. Explain its importance in this application.

   Hint

   Focus on component matching and layout design.

6. 6.

   Analyse an existing differential amplifier circuit demonstrating practical issues due to high common mode gain. Suggest modifications to improve performance.

   Hint

   Consider how the layout affects performance.
