Millimeter-wave anti-collision radars have been widely investigated in advanced CMOS technologies recently. 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,… (More)

—This paper presents two fully integrated binary phase-shift keying (BPSK) and quadrature phase-shift keying (QPSK) transceivers operating at-band [carrier frequency = 212 mW (Tx) and 166 mW (Rx) from a 1.2-V supply. Both cases are measured with link distance of 1 m and antenna gain of 24 dBi.
Modern high-speed wireless data links such as 60GHz RF and point-to-point communications activate research on Gb/s transceivers for V-band (50 to 75GHz) and W-band (75 to 110GHz). Conventional approaches in SiGe or III-V compounds simply consume too much power and occupy too large area, in addition to the integration difficulty. In CMOS realizations,… (More)
