WebThe paper presents an ultra-wideband, low-power frequency synthesizer for Ku-band FMCW radars. This ADPLL-based frequency synthesizer generates chirps with configurable rate from 0.4 to 3.2GHz/ms, up to 2GHz bandwidth in triangle or sawtooth mode. Adaptive loop bandwidth is adopted to reduce variations of the loop tracking characteristic during …

WebThis chapter describes a millimeter (mm)-wave all-digital PLL (ADPLL) design example for a 60-GHz FMCW radar application. The multi-rate ADPLL-based frequency modulator architecture provides wideband frequency modulation capability, which can be used for many mm-wave applications. WebFrequency-modulated continuous-wave (FMCW) signals-based radar systems can outrun the optical and ultrasound sensors in dark and severe weather conditions. FMCW radar systems require a fast settling frequency synthesizer to reduce the chirp signal’s inactive and modulation times. green man clifton campville opening hours
