Abstract

An input/output (I/O) circuit includes an electrostatic discharge (ESD) protection circuit electrically coupled with an output node of the I/O circuit. At least one inductor and at least one loading are electrically coupled in a series fashion and between the output node of the I/O circuit and a power line. A circuitry is electrically coupled with a node between the at least one inductor and the at least one loading. The circuitry is operable to increase a current flowing through the at least one inductor during a signal transition. The circuitry comprises at least one pre-driver stage having at least one output node, and the at least one output node of the at least one pre-driver stage is electrically coupled with at least one input node of a driver stage.
