Abstract: An electrostatic discharge (ESD) protection circuit is provided. The ESD protection circuit includes a transient-state detection circuit configured to generate a dynamic triggering signal based on a voltage change rate of a voltage on a first power rail; a voltage detection circuit configured to generate a static triggering signal based on the voltage on the first power rail; a trigger circuit configured to generate a discharge control signal based on the dynamic triggering signal and the static triggering signal; and a main discharge circuit configured to discharge an electric charge from the first power rail to a second power rail based on the discharge control signal.
