The research focus of the Circuits and Systems group is to introduce state-of-the-art innovations, which cover various technologies such as digital, analog and mixed-signal ICs, MMIC/RFIC, antennas, electromagnetic modelings and integrated multi-chip-modules into the design and implementation of modern electronic products/systems such as smartcard, RFID, software radio and WiMAX.
Our group is also actively engaged in industrial projects including the development of advanced RFID systems and components for consumer electronics products. In the last few years, the group has received over HK$ 25 Million from external funding agencies including industry and ITC (government-owned).
Our department is the first among all institutions in Hong Kong to introduce ASIC design into our undergraduate program and as a specialised field of research. Our major facility includes the most advanced RF Radiation Research Lab that is equipped with a 128-probe SATIMO near field spherical scanner, the most comprehensive communication tester and DASY5 dosimetric assessment systems which allows compliance testing of mobile phones with SAR limits. It is CTIA compliant and supports both TIS (Total Isotropic Sensitivity) and TRP (Total Radiated Power) measurements. It is ideal for testing mobile terminals, base station antennas as well as automotive antennas.
The VLSI and the microwave research laboratories are installed with a large number of workstations, PCs and a comprehensive and industrial standard suite of design software including Cadence, Mentor Graphics, Synopsys, ADS (advanced design system) and CST. State-of-the-art testing equipment such as logic analyzer, network/spectrum analyzer, multi-function signal generator, digital scopes, probe station, SAR tester and EMC chamber are also available.

研究重點是引入創新的技術,包括數字,模擬與混合訊號集成電路, 微波集成電路與射頻集成電路,天線,電磁學模型與多晶片模組技術等。研究包括電子產品和系統的設計和應用(如智能卡,射頻識別和WiMAX)。我們團隊是首批將特殊應用積體電路設計引入香港本科課程和研究領域。
我們團隊還積極參與各式各樣的工業項目,包括開發先進的射頻識別系統和消費電子產品。在過去幾年中,已從外部資金機構(包括行業和創新科技署(政府擁有))獲得超過2,500萬港元的資金。
我們團隊的主要設施包括最先進的射頻輻射研究實驗室,該實驗室配備128 個探頭的SATIMO 近場掃描儀 SG128。SG128 設施符合CTIA標準,並支持TIS(總全向靈敏度)和TRP(總接收功率)測量,非常適用於測試移動終端,基站天線以及汽車天線,是測量超大型天線的理想工具。設施也包括全面的通信測試儀和电磁波吸收比值測試系統,可以對移動電話進行SAR限值的測試。
其他設施還包括邏輯分析儀,網絡/頻譜分析儀,多功能信號發生器,數字示波器,探針台和電磁兼容性室等最先進的測試設備。 超大型積體電路和微波研究實驗室安裝了多台工作站和高效能電腦,軟件包括 Cadence,Mentor Graphics,Synopsys,ADS和CST等工業標準設計軟件。
