A 77/79-GHz Frequency Generator in 16-nm CMOS for FMCW Radar Applications Based on a 26-GHz Oscillator with Co-Generated Third Harmonic

This paper presents a digitally controlled frequency generator for dual frequency-band radar system that is optimized for 16 nm FinFET CMOS. It is based on a 21% wide tuning range,fine-resolution DCO with only switchable metal capacitors. A third-harmonic boosting DCO simultaneously generates 22.5-28 GHz and sufficiently strong 68-84 GHz...
