摘要：This article presents a CMOS-based, ultra-broadband frequency-modulated continuous-wave (FMCW) radar using a terahertz (THz) frequency-comb architecture. The high-parallelism spectral sensing provided by this architecture significantly reduces the bandwidth requirement for the THz front-end circuitry and ensures that the peak output power and sensitivity are maintained across the entire band of operation. The speed and linearity of frequency chirping are also improved by the comb system. An antenna-sharing scheme based on a square-mixer-first architecture is used, which not only leads to compa
