ABSTRACT:
An electrostatic discharge (ESD) protection circuit and method thereof is provided. The ESD protection circuit includes two clamping circuits, an inductor, a diode and a diode string. In addition to a voltage swing of an output voltage able to get rid of the influence of the ESD protection circuit, the invention reduces an ESD conduction path length and dissipates an ESD current swiftly by installing at least two clamping circuits, which significantly increases the effectiveness of the protection for large-signal circuits.
