Abstract
A repeater for open-drain bus communication and a system including the same is provided. The repeater includes at least one repeating unit having an A-side terminal connected to an A-side open-drain bus, and a B-side terminal electrically connected to a B-side open-drain bus. The repeater has a first mode to receive a signal at the A-side and to produce a signal at the B-side. The repeating unit includes a B-side accelerator element connected to the B-side terminal. The repeating unit when in a first mode includes a first control unit to, control the B-side accelerator element to pull up a voltage at the B-side when the voltage at the A-side surpasses a first threshold voltage during a rising edge of the voltage, and to subsequently control the B-side accelerator element to stop pulling up the voltage at the B-side when the voltage at the B-side surpasses a second threshold voltage.
