Latest Patents

Chien-Tzu Ko holds a patent for a "Pull-up voltage detection circuit and pull-up voltage detection method." This invention is designed for use in a serial bus, which includes a communication signal. During communication intervals, the communication signal is toggled based on a pull-up voltage, facilitating effective communication via an open-drain scheme. The circuit comprises at least one comparator for comparing the communication signal or a divided voltage with at least one reference voltage, generating comparison results. A selector circuit then chooses one of several predetermined voltages based on these results, establishing a logic threshold voltage that corresponds to the pull-up voltage. This innovation allows for accurate determination of the communication signal's logic state during the communication interval.
