Research interests
My current research interests mainly focus on energy-efficient wireless sensing and communications, including:
- Energy-efficient RF transceiver design, with a focus on high-performance amplifiers, nonlinear modelling, and integrated design of amplifier and antenna;
- Far-field wireless power transfer/harvesting, with a particular emphasis on low-power rectifiers and diode modelling;
- Backscattering technology for battery-free communications and sensing
