Abstract
A system and method relieves ESD requirements on devices in circuits of chips that are susceptible to being damaged from ESD through an external pad. For example, one of the devices can be NMOS transistors having drains (or sources) connected to the external pad(s) and no (or significantly small) current flows from their drains (or sources) to the corresponding pad(s). In order to protect such a device, an ESD protecting system is coupled between the NMOS device and the pad. The ESD protecting system can include an n-type transistor or a p-type transistor.
