科学研究
Research Themes
Digital-Assisted RF/Microwave/MM-Wave Integrated Circuits & Systems
With the aim to meet the requirement of low power & high efficiency wireless communication, the digital-assisted RF is the key solution. To increase the data-rates with enhanced bandwidth, microwave/mm-wave IC with digital-assisted techniques are the essential module in the whole system. New high efficiency architecture with novel low power circuits will be innovated and developed for minimizing the use of conventional digital/analog circuit functions by replacing them with digital equivalents RF/microwave/mm-wave, which are more amenable to scaling in advanced CMOS technologies.
Big-Data Transmission Integrated Circuits & Systems
Big-data (i.e., one Tb/s and beyond) transmission is the trend in the next-generation communication beyond 2020. Many applications of internet of everything (IoE) will improve the life-quality of human-beings and make the world connection closer. As one of the key sub-systems in the total big-data system, the on-chip transceiver demands novel proof-of-concepts to achieve requirements of high performance IoE system. Such transceiver aims to conquer new frontiers in terms of carrier frequency, signal processing, and RF semiconductor design.
On-Chip THz Circuits & Systems
THz communication is one of the trend for future talk between things & human-beings. The heart-key elements, i.e., THz IC, should be carefully developed considering the process limits from Si-based process. Novel unit circuit, i.e., resonator, with improved physical meaning is dramatically demanded for THz active circuits design. Besides, THz IC with sub-system implementation should be higly developed with novelty. Consequently, there is a great need for reliable and feasiable passive devices and high-speed ICs intended for THz frequencies.
Reconfigurable Passive Circuits & Systems
For the coming 5G & future communication, data-rates and frequency spectrum are the limitation. For the front-end implemetation, reconfigurable mechanism should be highly developed for the multi-mode and multi-band operation. Novel tunable passive with simultaneous frequency and bandwidth adjustment is the essential key component in pratical communication system, which still remains chanllenges for scientific research and development.
70 IEEE Journal (including TMTT, JSSC, MWCL, EL) & Conference (including IMS, EuMW, CICC, RFIC) Publications in RF/Microwave/mm-wave/THz fields

50 Patents, including 36 international patents, for wireless communication
2 international & successful product-series in backhaul & mobile industry with profits more than 1 billion dollars
