In general, I am interested in all kinds of research and design related to RF/analog and mixed signal circuit. I am especially interested in ultra low power circuits that enable sustainable green devices, which may contribute significantly to the solution of energy crisis that we are facing. I am also interested in designing high performance yet flexible RF front-ends to accomendate the trend of developing multi-mode multi-standard radio technology.


Energy Harvesting Active Networked Tags (EnHANTs), is a multi-discipline project aiming at realizing self sustainable networked devices that can operate over harvested energy. The EnHANTs tag features ultra low power operation by ultilizing Ultra-Wide Band (UWB) radio technology. The EnHANTs is a potential solution for the infrastructure of "Internet of Things" that enables ubiquitous networking and computing.

In this project, I have contributed significantly to the integration of our custom designed UWB radio chipset into the prototype platform that is used for verification of our protocol stacks and energy adaptive algorithms. My works range from RF circuit design and testing all the way up to development of physical layer driver for the UWB chips.

We have successfully demonstrated this in MobiSys '11 and we are also going to demostrate them in the coming SenSys '11.
