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...

An All-Digital PLL for Cellular Mobile Phones in 28-nm CMOS with -55 dBc Fractional and -91 dBc Reference Spurs

We propose a time-predictive architecture of an all-digital PLL (ADPLL) for cellular radios, which is optimized for advanced CMOS. It is based on a 1/8-length time-to-digital converter (TDC) of stabilized 7-ps resolution, as well as wide tuning range, and fine-resolution class-F digitally controlled oscillator (DCO) with only switchable metal...
