Micro-Radio Laboratory (u-Radio LAB) has focused on CMOS Integrated Circuit design since 1998. μ-Radio Lab’s research area consists of RF front-end, Baseband analog, Mixed-mode(Synthesizer, ADC/DAC), High speed optical circuits and Digital calibration techniques. 21 Ph.D and 7 master degree students are currently supervised by Professor Sang-Gug Lee. The Lab’s recent research topics include DTV tuner, Impulse-Radio UWB (IR-UWB) radar, Wake-up receiver, Digital RF system, Display semiconductor, FM receiver, Advanced transceiver system modeling, etc. Some of the research details are as follows. Digital TV Tuner. In line with digital convergence on video and TV technology, u-Radio laboratory has made persistent effort in DTV tuner IC development and developed DVB-T/DVB-H dual band tuner and ISDB-T tuner. Now the research phase moves to multi-standard DTV tuner development which covers ATSC, DVB-T, DVB-C, and Open-Cable. Impulse Radio UWB Application. Impulse Radio UWB (IR-UWB) rises as a core scheme in RFID/USN applications due to its advantages of high security, efficiency in low-speed data transmission, and high-accuracy distance measurement. μ-Radio laboratory developed low-power IR-UWB transceiver for IEEE 802.15.4a standard and low-power, low-cost, and low-complexity IR-UWB radar for movement detection. Wake-Up Receiver. Low power consumption is one of major design issues in wireless sensor networks due to the limited battery. The key issues in Wake-Up receiver design are ultra-low power consumption, extremely short latency, and reliability. μ-Radio laboratory has developed a few uA current consumption Wake-up receiver passing by three-time design experiences. Advanced Transceiver System Modeling. The research on the predictable SoC architecture and modeling is demanded in order to reduce IC development cost by reducing redundant fabrication chance and thus saving time at the same time. The research includes behavioral modeling for individual blocks, performance parameter extraction from the blocks and performance prediction with simulation. In addition, the predictable SoC architecture modeling research contains substrate coupling analysis and modeling. μ-Radio laboratory recently focuses on optimal RF architecture development for 3GPP LTE specification with an aid of Simulink simulator. With state-of-the-art research environment and frequent access to popular IC foundry, ？-Radio welcomes anyone who is interested in and gifted at IC design.
