PhD Student Jiayang Li breaks new ground with ISSCC 2025 paper acceptance

ISSCC, often dubbed the “Chip Olympics,” is the world’s leading forum for innovations in integrated circuit technology. It gathers top experts and major chip manufacturers like Intel, Nvidia, and Samsung, making it a prestigious stage for breakthroughs in chip design. Acceptance into this conference is a clear indication of the high impact and potential of the research being presented.

Jiayang Li’s paper, '35.3 A 30MHz Wideband 92.7dB SNR 99.6% Accuracy Bioimpedance Spectroscopy IC Using Time-to-Digital Demodulation with Co-Prime Delay Locked Sampling' focuses on developing a revolutionary bioimpedance spectroscopy chip. In simple terms, this chip is a tiny, power-efficient device designed to measure how body tissues resist electrical signals—a key factor in biomedical diagnostics. Despite its small size of only 1.6 mm², the chip delivers remarkably precise measurements and operates at extremely low power. Jiayang’s innovative approach uses a new method to capture electrical signals quickly and accurately, which could pave the way for more advanced and reliable biomedical devices in the future.

This breakthrough not only highlights the technical excellence at UCL but also opens up exciting possibilities for enhancing biomedical applications, potentially benefiting a wide range of healthcare technologies.
