Design monitoring device for Ultra-High Voltage Transmission System. Analog and Digital circuit design. DC/DC, AC/DC, ADC, FILTER. Microcontroller system design. Theory research and build the model. Establish prototype and test. Improve, update, and debug previous design.

In GFUS 130nm process with 1.2V VDD. The system includes four parts: Phase Frequency Detector(PFD), Low Pass Filter, Voltage-Controlled Oscillator, Divider. Max Input signal: 100MHz, Lock range is around 20MHz.

Design an op-amp which can drive a complex load with an out-put buffer. In GFUS 130nm process with 1.2V VDD, 100M Bandwidth, and 70dB Gain. Use BMR to bias the two stages amplifier: Cascode differential amplifier, and push-pull. Applying schematic and layout in Silvaco.

Assist the professor to answer the students' question. Assist the professor to set up and design the lab. Assist the professor to correct the homework.

Use VHDL to write the top-level design and RTOS to control the system Create a user interface to control the FPGA Use the I2C protocol to operate the EEPROM

A system can detect fatigue level of drivers Use Circuit Python to collect the data. Use Node-red to make the connection between the Circuit Python and IoT platform. Use MQTT protocol.

Collect and analyze signals through Ni MyDAQ. And use LabVIEW to write the code to make the interactive system.

QL + company, established by the retired officers of the US Air Force, commissioned us to design an electric bicycle project. Help the disabled people who love riding to participate in riding activities, solve the problem that they can't keep up with others on the uphill, and eliminate the potential risk of push bars. In this project, we completed the project proposal, product design and analysis, test analysis, and final report. Every week, our team communicates with customers about the project progress, listens to customers' feedback, and constantly improves the design.

We designed a tabletop sterilizer. After making the design scheme, we do the market research on the product, make the forecast on the sales volume, and use the analysis method learned in class to carry out the economic analysis. Finally, after the evaluation of three economics professors, our project got an A rating.

We make solutions according to the project requirements. Students of a project management course in a university in the UK are our clients, supervise our projects and make requirements of improvements. In this project, we developed the project charter, schedule, used FMEA to analyze the potential risks, and completed the summary report and project presentation.
