该论文提出了一种在65nm CMOS工艺中实现的太赫兹FMCW梳状雷达，通过创新的梳状架构将信号带宽扩展至100GHz，解决了传统CMOS太赫兹雷达带宽受限的问题，适用于高精度工业机器人和小缺陷检测等场景。
systems have driven the operation frequency to terahertz (THz) due to the shorter wavelength and larger bandwidth [1-5]. However, conventional single-transceiver FMCW radar chips only provide limited signal bandwidth (<70GHz [1-5]), especially when implemented using CMOS technologies with low fT and fmax. Therefore, prior THz integrated radars are based on compound semiconductors [2-4] and have severely degraded performance near the band edges. That not only limits their applications in high-accuracy scenarios like industrial robotics and small-defect detections, but also poses tradeoffs between bandwidth and detection range. To break such limitations, this paper adopts a frequency-combbased scalable architecture using a paralleled transceiver array to cover an
