Abstract

An accumulator based all-digital PLL for linear FMCW chirp generation is proposed. Operating at a Reference Frequency of 128 MHz the Phase Noise at 100 kHz offset measures -80 dBc/Hz. The proposed chirp linearization scheme allows for a wide range of chirp periods from 40 us up to 200 ms with an RMS Frequency Error of down to 7.26 kHz for slow and 882 kHz for fast chirps. Without dithering, the digitally, switched capacitor controlled oscillator presented in this work achieves an average step size of below 25 kHz while ranging from 11.596 GHz to 12.783 GHz.
