A research team led by Prof. Junghyup Lee of the Department of Electrical Engineering and Computer Science at DGIST has become the first in the world to develop a “time-interleaved noise-shaping SAR ADC (analog-to-digital converter)” semiconductor chip capable of simultaneously measuring multiple biosignals, including electrocardiograms (ECG) and electromyograms (EMG). The team developed this technology in an actual semiconductor chip and successfully completed functional validation. Their findings were presented at the IEEE Symposium on VLSI Technology & Circuits (VLSI 2026), held in Honolulu, June 14–18.
