4.3. Foundational Design Principles

Try these first

1. 1.

   What is the purpose of domain isolation?

   Hint

   Think about why signals may affect each other.

2. 2.

   What does ground isolation aim to minimize?

   Hint

   Consider grounding techniques.

3. 3.

   What is the main benefit of domain isolation in mixed signal systems?

   • Reduce cost
   • Avoid interference
   • Simplify design

   Hint

   Focus on the primary function of isolation.

4. 4.

   True or False: Ground isolation can not help minimize ground bounce.

   • True
   • False

   Hint

   Think about the objectives of grounding techniques.

5. 5.

   Design a system with specifications that require both analog and digital qualities. How will you ensure each domain functions optimally while interacting?

   Hint

   Think about the challenges of mixing the two domains.

6. 6.

   You are facing a jitter problem in an ADC setup causing inaccurate readouts. List steps to troubleshoot this scenario.

   Hint

   Recall the sources of jitter and mitigating strategies.
