Research Goal: Complete Sensor System IC

We are focusing on a complete sensor system that requires both analog and digital circuit designs and even device levels.

Audio Signal Processing IC

Speech recognition front-end beamforming IC (VLSI 2019, CICC 2020, ISSCC 2022, JSSC 2024)
Our speech recognition front-end achieves a novel beamforming algorithm, multi-mode beamformer, and ADC.

Efficient keyword spotting IC optimized with the multi-mode ADC

Drone ego-noise specific beamforming and AI denoising

Analog to Digital Converter (ADC)

Multi-mode 3rd order delta-sigma ADC for audio application (ISSCC 2022, JSSC 2024)
Our focus is on high-resolution ADC with an adaptive performance mode. This especially targets the speech recognition application.

SAR-assisted Pipeline ADC (VLSI2023, OJSSC2024 ,VLSI 2025)

Bio-sensor System IC

Miniaturized pH sensor system IC (VLSI 2019)
Our miniaturized pH sensor system includes an Ion-sensitivity FET (ISFET) post-fabrication in the clean room.
