Latest Patents
One of his latest patents is a wired transmitter with overvoltage protection. This invention includes a digital-to-analog converter (DAC) and a line driver. The DAC generates first output signals based on a digital code, with circuits operating in different voltage domains. The line driver, functioning in the second voltage domain, generates second output signals according to the first output signals. Each component is implemented using transistors that correspond to the first voltage domain.
Another notable patent is an audio player device and its startup method. This device features a DAC that converts audio data into two signals. A startup circuit gradually increases the startup voltage according to a reference voltage over a predetermined period. The multiplexer outputs the startup voltage as a control voltage during this period and switches to the reference voltage afterward. The output amplifier generates an audio signal based on the control voltage and the two signals, setting a common mode voltage for optimal performance.
