1.4. Challenges in Mixed Signal Circuit Design

Try these first

1. 1.

   What is noise coupling?

   Hint

   Think about how digital signals can disrupt analog ones.

2. 2.

   Why is power integrity important?

   Hint

   What happens if the voltage fluctuates?

3. 3.

   What is noise coupling?

   • Digital noise that helps analog signals
   • Interference of digital noise with analog signals
   • An enhancement technique for analog signals

   Hint

   Consider how digital actions might affect sound or other analog shapes.

4. 4.

   True or False: Mixed signal circuits can function well without considering power integrity.

   • True
   • False

   Hint

   What happens when different voltages are at play?

5. 5.

   Design a mixed signal circuit for an audio application while ensuring minimal noise coupling and adequate power integrity. Detail your design choices.

   Hint

   Focus on loud noise sources and sensitive analog processors and how to separate them.

6. 6.

   Develop a comprehensive testing strategy for a mixed signal circuit that includes both analog and digital components.

   Hint

   Different components often require different assessable features.
