• Carried out simulation test of the I2C programs by adopting modelsim

• Accomplished the whole procedure of the VLSI design

• Experience the whole procedure of the design and fabrication of the Analog-to-Digital Converter: circuit design, optimization of speed and energy, post-simulation, tape-out, testing and encapsulation 

• Learn the standard parameter in IC design and the basic circuit topology optimization of analog integrated circuits

• Complete the circuit design of the mix-structured pipelined-SAR ADC

• Study the rapid-converging digital calibration technology of high-powered converter

• Ease the design constraints of high-powered ADC from many aspects, e.g., structure, property, area and power consumption

• Serve as the research assistant of Prof. Luo and do frontier research of micro-nano devices based on lowdimensional semiconductor nanostructures

• Do characterization and fabrication of the MAPbI3 perovskite/Si heterojunction photodetector arrays for image sensing application

• Conduct fabrication and structural simulation of the Graphene/GaAs and Ga2O3/GaAs integrated photodetector devices

• Mastered static and dynamic properties of digital logic and studied CMOS scaling and energy components

• Learned the principles in building digital logic in static CMOS and PTL, gate sizing and its application

• Used the design expertise acquired in group to design the algorithm, determine the circuit topology and choose logic style that best optimizes the delay-energy metric of the Absolute-value Detector

• Identified input vectors that will exercise critical path, sized the gates for minimum delay and did VDD scaling

• Composed a paper related to the comparator’s offset based on the above study and published it as the first and corresponding author
