本文提出了一款采用40nm CMOS工艺的60GHz接收机，用于离散载波室内定位系统。通过降低处理带宽和稀疏带宽功率分配，在4米范围内实现了毫米级测距精度，解决了高带宽带来的基带功耗问题。
recently gained a lot of attention. Its broad bandwidth, combined with a high allowed transmitted power level, provides an excellent opportunity for numerous applications, among others high-precision ranging and localization. Despite being readily available at 60GHz, high bandwidths come with a significant power penalty in the baseband. The presented work brings a solution that delivers high ranging precision at heavily reduced processing bandwidths and sparse-bandwidth power allocations. Classic ToA ranging and localization applications, such as FMCW, wideband equivalent-time sampling and successive-approximation radar (SAR), use single-carrier (SC) schemes [1-3] with power spread over a wide bandwidth to achieve precision. Moreover, they often require TX-RX carrier phase-locking
