Latest Patents

Among his latest contributions is the patent for a "Switching amplifier incorporating return-to-zero quaternary power switch." This invention introduces a switching amplifier that utilizes a quaternary input control signal. This signal provides four distinct levels (1, 0H, -1, and 0L) which are coupled to an H-bridge amplifier, enabling error cancellation in the output signal of the switching amplifier. This technology enhances operational efficiency through a three-level sigma-delta modulator, which simplifies the detection of zero states while minimizing power consumption.

Additionally, Hsu has developed a patent for a "Sigma-delta digital-to-analog conversion system and process." This system offers a method for converting digital signals into analog signals efficiently. It incorporates a series of components including a reconstructor-resampler, a combiner, and a modulator, all working together to produce a high-quality analog output signal. The method ensures that the modulator operates at a fixed frequency, independent of the sampling frequency of incoming digital signals, resulting in a precise and reliable conversion process.
