Power Integrity Analysis Services in PCB Design
As electronic devices continue advancing with higher speed and lower voltage operations, maintaining power integrity is crucial. Fluctuations and noise in power delivery can lead to functional failures. Power integrity analysis evaluates the power distribution network to identify impedance problems and ensure clean power delivery.
Several factors make power integrity vital:
- Higher currents required at lower voltages
- Increased power density in constrained PCB area
- Complex power plane splits for multiple voltage rails
- Sensitive ICs with small noise margins
Proper power integrity techniques are essential to avoid issues like Power/ground bounce during switching, supply voltage fluctuations, resonances between power planes and excessive IR drops.
