ESD protection device of the output driver stage

摘要

I disclose ESD at the output driver stage of the semiconductor chip to (Electro-Static Discharge) protection device. And comprise a NMOS transistor and the source PMOS transistor and a source connected to the first power source is connected to the second power supply, ESD protection devices of the output driver stage of the invention, the internal circuit to the gate of each MOS transistor The output signal is applied respectively, in the ESD protection device of the output driver stage coupled to an output pad, the drain of each MOS transistors separation between the gate poly and the contact formed on the drain region of the MOS transistor relatively larger than the value by (Design Rule) design rule spacing, was decided.
