9.4.3. Layout and Parasitics

Try these first

1. 1.

   What is parasitic capacitance?

   Hint

   Think about conductors that are close together.

2. 2.

   Why is layout important in mixed-signal design?

   Hint

   Consider how one section affects another.

3. 3.

   What is the primary purpose of layout in mixed-signal design?

   • Increase complexity
   • Minimize interference
   • Maximize component density

   Hint

   How does one part of the circuit influence another?

4. 4.

   True or False: Parasitic effects are advantageous in circuit design.

   • True
   • False

   Hint

   Consider whether these effects help or hinder performance.

5. 5.

   Evaluate a poorly designed mixed-signal circuit layout that suffers from cross-talk. What techniques would you employ to correct these issues?

   Hint

   Think about how physical placement changes performance.

6. 6.

   Design a layout for a mixed-signal integrated circuit that minimizes parasitic effects while maintaining performance. Outline your considerations.

   Hint

   Focus on logical separation and layout efficiency.
