Circuit Techniques for Radar and Phased Array
This session presents circuit techniques for radars and phased arrays, achieving good energy and area efficiency, wider bandwidth with improved detection range and resolution. A 1TX/4RX FMCW radar chipset exploits multi-band to achieve an angular resolution of 6deg. Baseband techniques are then presented, achieving 800MHz signal bandwidth for phase array and 7.5cm resolution for PMCW with good area and energy efficiency. Finally, two radars for vital-sign detection, with multi-mode IR-UWB radar achieving detection range up to 10m, and another combined FMCW and Doppler radar work with shared building blocks, achieving small chirp frequency error of 0.04%.
