Abstract

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 signals to satisfy short-range radar (SRR) and medium/long range radar (M/LRR) requirements. The 20.2 mW DCO emits -97 dBc/Hz at 1 MHz offset from 77 GHz,while fully satisfying metal density rules. It occupies 0.07 mm²,thus demonstrating both 43% power and 47% area reductions. The phase noise and FoM_T (figure-of-merit with tuning range) are improved by 1.8 dB and 0.2 dB,respectively,compared to state-of-the-art.
