For adaptive electrostatic discharge (ESD) protection, an integrated circuit device having an adaptive electrostatic discharge (ESD) protection, has an external connection pin to be protected from ESD; an external ground connection pin; an adaptive electrostatic discharge (ESD) protection circuit having: an ESD protection N-metal oxide semiconductor (NMOS) transistor having drain connected to the external connection pin and a source and bulk connected to ground; a resistor coupled between a gate of the NMOS transistor and ground; a first PMOS transistor having a source coupled to a gate of the NMOS transistor and a drain connected to ground; a first capacitor having a first terminal connected to the external connection pin and a second terminal that is coupled with the gate of the NMOS transistor, therein the first capacitor within the adaptive ESD protection circuit is the only capacitor connected to the external connection pin.
