Abstract

An electronic device having an LV-well element trigger structure that reduces the effective snapback trigger voltage in MOS drivers or ESD protection devices. A reduced triggering voltage facilitates multi-finger turn-on and thus uniform current flow and/or helps to avoid competitive triggering issues.
