防止电荷耦合的ESD保护

ESD protection against charge coupling
Abstract:
This document discusses among other things apparatus and methods for reducing ESD damage to buffer circuits. In an example, an output buffer can include an output, a first transistor configured to couple the output to a high logic supply rail, a second transistor configured to couple the output node to a low logic supply rail, pre-driver logic configured to drive a gate of the first transistor and a gate of the second transistor, and a first resistor configured to reduce electrostatic discharge (ESD) induced current between the first transistor and the pre-driver logic.
