Power Integrity Analysis: What PDN has to achieve? - Part 3

 The Power Distribution Network (PDN) in a board must achieve the following:

• Provide clean power to the chips connected. This meant voltage must remain stable with minimal fluctuations in different scenarios like switching
• Ensure adequate current reaches different parts of the circuit without excessive resistance or losses.Maintains low impedance pathways for power delivery, improving efficiency and reducing voltage drops.
• Ground bounce must be minimized
• Reduces electromagnetic interference (EMI) and power supply noise that could disrupt signal integrity.
