4.2. Key Integration Challenges

Try these first

1. 1.

   What is noise coupling?

   Hint

   Think about what happens during digital switching.

2. 2.

   What is ground bounce?

   Hint

   Consider how different circuits share the same ground.

3. 3.

   What does noise coupling refer to?

   • A. Voltage fluctuations
   • B. Digital noise affecting analog circuits
   • C. Ground bounce

   Hint

   Focus on the interaction between digital and analog.

4. 4.

   True or False: Ground bounce can lead to improved performance in analog components.

   • True
   • False

   Hint

   Think about the effects of shared grounds.

5. 5.

   Design a mixed-signal PCB with at least three techniques addressing noise coupling and grounding issues. Detail your choices and their expected benefits.

   Hint

   Think about how each choice isolates or protects the analog signals.

6. 6.

   Analyze a PCB layout where analog and digital sections are near each other. Identify potential problems and propose layout changes to improve performance.

   Hint

   Focus on layout impact on signal integrity.
