Use PDS analysis to improve design performance characteristics

Posted: 04 Feb 2007     Print Version  Bookmark and Share

Keywords:power delivery system  PDS analysis  IC power supply  PDS design 

Power delivery system (PDS) analysis and design have become increasingly important in the communication, networking and consumer electronics industries.

In the International Technology Roadmap for Semiconductors, IC power supply voltage continues to drop with the inevitable scaling of VLSI technology. The migration from 130nm to 90nm has shrunk supply voltages to 1.2V and below, and considerably increased currents supplied to devices through the PDS.

These developments pose challenges to PDS design - from DC IR drop to AC dynamic voltage fluctuation control - especially as margins get tighter.
