Project

  1. An 85-230VAC input and 3.3-4.6VDC output AC-DC converter
    Oct. 2023 - Oct. 2024
    • A Sigma-Floating-SC topology is proposed to achieve 81.3\% peak efficiency and 1.52W maximum output power.
    • Up to 10% increased efficiency over a large load current range, compared with prior works.
    • The design is fabricated in a 180nmBCD process and the manuscript has been accepted by ISSCC 2025.
  2. HIDDEN
    Oct. 2023 - Oct. 2024
    • The manuscript has been submitted to CICC 2025.
  3. A fast-transient response single-input-multiple-output DC-DC converter
    Sep. 2022 - Oct. 2023
    • The design utilize an auxiliary capacitor stacked with the input power source to increase the inductor charging speed and thereby improve the transient response.
    • Collaborated with 3Peak INCORPORATED.
  4. Low-power, high transient response LDO design without off-chip capacitors
    Nov. 2020 - Aug. 2021
    • Developed a bandgap with 1.2V voltage reference and 50nA current reference, whose power consumption was less than 200nW, in the temperature variation range of -40 to 125 degrees celsius.
    • Developed a circuit of super positive feedback and self-bias amplifier, with static power consumption of 3-7uA and high bandwidth of 80M-160MHz.
    • Won the first prize of the National University Student Integrated Circuit Innovation and Entrepreneurship Competition in Southwest Devision (2021).
  5. Smartphone-based Analysis of Non-destructive Apple Brix Measurement
    Apr. 2021 - Aug. 2021
    • Designed an optical system using Zemax OpticStudio to achieve Czerny-Turner Spectroscope structure using a positive (converging) lens, two spherical mirrors, a blazed grating and a linear CCD.
    • Designed a CCD driver board including a Xilinx FPGA, a Toshiba linear CCD, a high-speed and high-precision ADC and so on to capture light spectra and transmit digital spectra data to smart phones.
    • Programmed verilog HDL codes on Xilinx FPGA to drive CCD and ADC, besides communicating with smart phones by USB protocol.
    • Won the second prize of the National University Student’s Opt-Sci-Tech Competition (2021).
  6. Intelligent Biological Microscope
    Apr. 2020 - July. 2020
    • Designed a multi-method of resizing and merging limited images under microscopes to make up a full cell image.
    • Migrated the M2Det algorithm to suit the blood cell recognition, segmentation, and counting.
    • Developed a dataset of blood cells with five classifications including neutrophils, lymphocytes, monocytes, eosinophils and basophils.
    • Won the first prize of the 8th National University Student’s Opt-Sci-Tech Competition (2020) and the first prize of China-U.S. Young Maker Competition in Chengdu Division (2020).
  7. Intelligent Device to Protect Children left in Cars
    Apr. 2019 - July. 2019
    • Designed a multi-model network merged by AgeNet and Yolo-v2 to detect children left in cars.
    • Used sensors such as temperature and humidity sensor, Oxygen sensor and AIoT to send data to private servers.
    • Programmed a mobile app to receive warnings sent by servers to remind children’s guardians of the states in cars about their children.
    • Won the third prize of the National University Student’s Opt-Sci-Tech Competition (2019).
