Latest Patents
One of Zhun Chen's latest patents is a wired transmitter with overvoltage protection. This innovative device includes a digital-to-analog converter (DAC) and a line driver. The DAC generates first output signals based on a digital code, with distinct voltage domains for its circuits. The line driver, operating in the second voltage domain, generates second output signals according to the first output signals. This design ensures efficient performance while maintaining safety against overvoltage.
Another significant patent is for 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 during a predetermined period. The multiplexer outputs this startup voltage as a control voltage, which is then switched to the reference voltage after the period elapses. The output amplifier generates an audio signal based on the control voltage and the two signals, enhancing the audio experience.
