多电源和多地的片上ESD保护

On-chip ESD protection for multiple V_(dd) & Gnd

介绍了集成电路设计中ＥＳＤ保护的基本原理和几种常用的保护方法并比较其优劣。提出了在多电源、多地时特殊的ＥＳＤ保护结构（栅耦合结构及共用泄放回路），以及该结构在不同应用中的变化。

The basic ESD protection theory in IC design, the normal protection structure and the advantage or disadvantage are introduced. The special ESD protection idea (gate-coupled and CDL) for multiple Vdd and Gnd, and the different applications are discussed also.
