Current Research Areas

Low Power Circuits (Sensor Interface, Analog/Mixed-signal Integrated Circuits)
Advanced fabrication technologies and emerging systems like quantum computer, sensing networks have new requirements on the circuits in terms of power consumption, operating environment and precision. We are exploring novel circuit design techniques to maintain the ASICs' performance under extreme conditions like high/low temperature, strong EM irradition, etc.

Passive Sensing Platform for Internet of Things (IoT)
To enable the vision of IoT and AI powered future world, the front-end devices, sensors, are of utmost importance to collect and feed data into the AI engine to perform analysis and control. Given the number and diversity of the target sensing spots, the sensor node should be low-cost and maintainance-free. We are working on new passive sensing platforms integrating power, sensor, communication as well as coarse data process on a single substrate.

Heterogeneous Sensors (Chemical, Biomolecular, MEMS) for Biomedical Applications
To develop enabling technologies and miniaturized devices which bring benefits to people that are not accessible to regular medical screening, various sensors are required to capture different bio-signals. Our group are exploring the interface and integration techniques to design heterogeneous biomedical sensing system.
