The synthesizer achieve the phase noise of -88.47 dBc/Hz at 1-MHz offset, the reference spurs of -49 dBc and the fractional spurs -50 dBc, consuming 84mW from 1.4-V supply. Utilizing a delta-sigma fractional-N synthesizer as the FMCW generator, the synthesizer linearly modulates the carrier frequency across a range of 220 MHz. Further integration has been made with the transceiver front-end as well as an FFT-based baseband processor; this prototype provides a maximum detectable distance exceed 100 meters for a mid-size car while consuming 392 mW from a 1.4-V supply.2894289 bytesapplication/pdfen-US連續波頻率調變雷達24-GHz分數型頻率合成器快速傅利葉轉換Frequency modulated continuous-wave (FMCW) radar24 GHzfractional-N synthesizerfast Fourier transform (FFT)thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/256824/1/ntu-100-R98943136-1.pdf
