Device and method for operating the same

A device, comprising:

• a pad configured to receive an input signal;
• an ESD protection circuit coupled to the pad;
• an ESD detector coupled to the pad, configured to detect the input signal, and configured to generate a detection signal in response to an ESD event being detected;
• a bias generator coupled to the ESD detector and comprising a transistor configured to receive the detection signal and a reference voltage signal, wherein the transistor is configured to transmit, in response to the detection signal, the reference voltage signal as a bias signal;
• and
• an ESD driver comprising a plurality of transistors coupled to each other in series, wherein when the ESD event occurs, the plurality of transistors are controlled according to the bias signal and a logic control signal so that voltage drops across each transistor of the plurality of transistors are substantially the same.

A method, comprising:

• generating a detection signal in response to an ESD event being detected;
