Abstract
A device is disclosed herein. The device includes an electrostatic discharge (ESD) detector, a bias generator, and an ESD driver including at least two transistors coupled to each other in series. The ESD detector is configured to detect an input signal and generate a detection signal in response to an ESD event being detected. The bias generator is configured to generate a bias signal according to the detection signal. The at least two transistors are controlled according to the bias signal and a logic control signal, and the input signal is applied across the at least two transistors.
