Shiuh-hua Wood Chiang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Solid-state charge detector
    Patent number: 11443930
    Abstract: The present invention is a system and method for providing a charge detector that utilizes small feedback capacitors in a low-noise, high-gain, system that combines a differential topology in a solid-state amplifier implemented in a complementary metal-oxide semiconductor (CMOS) process with active reset, thereby achieving high dynamic range and robust operations. A custom optoelectronic system is used to measure gain, and while operating at a sampling frequency of 10 kHz, the active reset extends the dynamic range of the charge detector.
    Type: Grant

    Date of Patent: September 13, 2022
    Assignee: Brigham Young University
    Inventors: Yixin Song, Shiuh-hua Wood Chiang, Aaron R. Hawkins, Daniel E. Austin
  • Time-interleaved successive approximation register analog to digital converter with grouped digital to analog capacitors
    Patent number: 11101814
    Abstract: The present invention is a system and method for providing a modified Digital-to-Analog converter (DAC) for use in a time-interleaved successive-approximation-register (SAR) analog-to-digital converter (ADC), the DAC including grouping of capacitance electrodes by Bit in a DAC, thereby reducing parasitic capacitances, and substantially improving power efficiency and speed to operate at GHz frequencies.
