Abstract 

—Millimeter-wave sensors perform robust and accurateremote motion sensing. We propose a 28 nm CMOS RadarTX that modulates a 79 GHz carrier with a 2 Gsps Pseudo-Noisesequence. The measured modulated output power at 79 GHz in4 GHz BW is higher than 11 dBm (27 C), while the spuriousemissions are below 20 dBc, fully satisfying the spectral maskregulations. The output RF BW where we can lock the injection-lockedLO is 13 GHz. Overall, the TX draws 121 mW froma 0.9 V supply resulting in a record efficiency above 10%. Moreimportantly, the TX is functional up to 125 C still providing morethan 7 dBm output power over the same RF BW.
