This paper presents a fully integrated 77GHz FMCW radar system in 65nm CMOS. The FMCW radar transmits a continuous wave which is triangularly modulated in frequency and receives the wave reflected from objects. As can be illustrated in Fig. 11.2.1, for a moving target, the received frequency would be shifted (i.e. Doppler shift), resulting in two different offset frequencies f+ and f- for the falling and rising ramps. Denoting the modulation range and period as B and Tm, respectively, we can derive the distance Rand the relative velocity V R as listed in Fig. 11.2.1, where fc represents the center frequency and c the speed of light. ©2010 IEEE.[SDGs]SDG16Advanced CMOS; Anticollision; Center frequency; Continuous Wave; Doppler shifts; FMCW radar; Fully integrated; Moving targets; Offset frequencies; Relative velocity; Speed of light; CMOS integrated circuits; Computer crime; Radar; Radar systems; Continuous wave radarconference paper10.1109/ISSCC.2010.54339512-s2.0-77952114331https://www.scopus.com/inward/record.uri?eid=2-s2.0-77952114331&doi=10.1109%2fISSCC.2010.5433951&partnerID=40&md5=8bd6eea801504bdf9c9a85ccde0a8b24
