1. A device, comprising:
a bias generator comprising a first transistor;
an electrostatic discharge (ESD) driver comprising a second transistor and a third transistor coupled to each other in series; and
a logic circuit configured to generate a logic control signal,
wherein a first terminal of the first transistor is configured to receive a reference voltage signal, a control terminal of the first transistor is configured to receive a detection signal in response to an ESD event being detected, a second terminal of the first transistor is coupled to a control terminal of the third transistor, and a control terminal of the second transistor is configured to receive the logic control signal.
