Abstract: A 10-GHz sub-sampling phase-locked loop (PLL) (SSPLL) with wideband low-noise frequency modulation for frequency-modulated continuous-wave (FMCW) radar applications is presented. It uses a low-power charge-integrating digital-to-analog converter (QDAC) to tune the voltage-controlled oscillator (VCO) in… read more here.

Abstract: This letter presents a fractional-N frequency synthesizer with an ultrawideband continuously tuning range of 32.4% centered at 26.85- and 8.7-GHz chirp for frequency-modulated continuous-wave (FMCW) radars. The synthesizer uses a fractional-N 9-GHz charge-pump phase-locked loop… read more here.
