ABSTRACT:
Adaptive electrostatic discharge (ESD) protection of a device interface has very good ESD robustness when it is handled or when installed into or removed from a system. And has robust immunity to DPI, electromagnetic interference (EMI) and the like, when it is operational in a system. There is a significant capacitive coupling between the drain and gate of a ESD protection metal oxide semiconductor (MOS) device to enhance ESD protection and lower snap back voltage thereof whenever there is no (or a low level) DPI on the external connection to be protected. Whereupon when a significant DPI/EMI signal is detected on the external connection, the capacitive coupling between the drain and gate of the MOS ESD protection device is disconnected, bypassed or attenuated so that DPI/EMI immunity of the device is enhanced.
