This paper proposed a techniqe to realize automatic fast coarse tuning of the wide-band VCO with SC-bank, which seems to be the fastest!!!


Abstract—This paper reports an agile VCO frequency calibration
technique and its application on a 10-GHz CMOS integer-N
phase-locked loop. The proposed calibration method accomplishes
efficient search for an optimum VCO discrete tuning curve among
a group of frequency sub-bands. The agility is attributed to a proposed
frequency comparison technique which is based on measuring
the period difference between two signals. Other mixedsignal
circuits are also developed to facilitate this approach. The
PLL incorporating the proposed calibration technique is implemented
in a 0.18- m CMOS process. The measured PLL phase
noise at 10 GHz is 102 dBc/Hz at 1-MHz offset frequency and
the reference spurs are lower than 48 dBc. The PLL consumes
44 mW in the low-current mode. The calibration time is less than 4 us.

如果有哪位能提供类似的能够应用到delta-sigma FS中的技术资料，将不胜感激！
