70.1.1. Single-Ended vs. Differential Signaling and Basic Model of a Differential Amplifier

Try these first

1. 1.

   Define single-ended signaling in your own words.

   Hint

   Think about how many terminals are involved and how they relate to ground.

2. 2.

   What is the main advantage of differential signaling?

   Hint

   Consider the operational environment of the amplifiers.

3. 3.

   What does a single-ended amplifier compare its input signal against?

   • Another signal
   • Ground
   • AC voltage

   Hint

   Consider how the terminals are set up in the circuit.

4. 4.

   True or False: Differential amplifiers can effectively reject common-mode signals.

   • True
   • False

   Hint

   Think about their operational characteristics.

5. 5.

   Design a circuit that combines both single-ended and differential amplifiers. Explain the role each component plays and how you would manage noise and signals.

   Hint

   Think about the benefits of each amplifier's design.

6. 6.

   Considering a case where a differential amplifier receives two signals with a high level of common noise, outline a step-by-step approach to minimize this noise.

   Hint

   Reflect on noise cancellation methods.
