Latest Patents

Hipolk Lu holds a patent for a "System of multi-channel shared resistor-string digital-to-analog converters and method of the same." This system includes a time-sharing interpolator that converts multi-channel digital audio input at a low sample rate to a high sample rate output. Additionally, it features a time-sharing sigma-delta modulator that modulates the digital audio input, resulting in a multi-channel digital audio output with a shorter sample word length. The system also incorporates multi-channel shared resistor-string digital-to-analog converters that transform the digital audio input into a staircase analog signal output. To further enhance the quality, a low-order RC filter is used for each channel to attenuate out-of-band noise, particularly high-frequency residue images.
