Evaluate clamping voltages for ESD protection

Posted: 03 Sep 2007 ?? ?Print Version ?Bookmark and Share

Keywords:ESD protection in handsets? clamping voltages? positive and negative pulse?

Designers of handheld products such as cellphones, digital cameras, MP3 players and PDAs are constantly challenged to provide more functionality in smaller form factors while reducing the overall system cost. IC designers have eased this trend by improving the speed and performance of their devices while decreasing the size of silicon real estate. However, the reduced dimensions of IC features have resulted in devices that are more susceptible to damage from ESD voltage.

This trend can have a negative impact on the reliability of the end product and can increase the likelihood of field failures. As a result, designers of handheld products are challenged to find cost-effective ESD solutions that can clamp to lower voltage levels to maintain high reliability.
