Intelligent mm-Wave Front-Ends: Bridging High-Resolution Radar, Wireless Communications, and Biomedical Sensing

Technical seminar by Dr. Yanjie (Jay) Wang, Chair Professor and Associate Dean of the School of Microelectronics at the South China University of Technology (SCUT) with the following abstract:

This talk presents a wideband millimeter-wave (mm-wave) phased-array transceiver (TRX) front-end in CMOS designed for high-resolution radar sensing and wireless communications. We explore a TRX architecture featuring high-resolution, calibration-free phase shifters integrated with PAs, paired with a noise-canceling LNA receiver to maximize system dynamic range. To minimize silicon footprint and facilitate compact phased-array scaling, a reconfigurable bidirectional PA/LNA topology is presented. A key innovation includes the use of AI-driven passive component matching networks, employing machine learning to optimize complex impedance transformations across wide bandwidths. Furthermore, the talk extends these high-efficiency design principles to the healthcare sector, discussing our recent research on a low-power, wirelessly powered multi-band RF antenna front-end tailored for non-invasive biomedical <a href="http://sensing.
