혼성신호 IC 연구실

We build up hardware in the form of Integrated Circuits and also develop fundamental design techniques to realize portable and energy-efficient systems. Our ongoing research includes Brain-Computer Interfaces, Photon-Counting/DNN-Assisted Imagers, Bio-sensor Platforms, and Data Converters. [2025 July] Junghyun's work on Zoom ADC is invited to the JSSC (VLSI Special Issue). [2025 Mar] Prof. Chae presents the Photon-Counting SPAD X-ray Sensor at the Image Sensors Europe. [2025 Feb] Prof. Chae presents the highlights of energy-efficient ADCs at the ISSCC forum. [2024 Oct] Prof. Chae gives several lectures at the Fudan University, Macao University, and ICSICT 2024.
