Abstract
The present invention discloses a two-step VCO calibration method. The two-step VCO calibration method, comprising power-on calibration, used to provide a coarse VCO tuning; real-time calibration, used to provide a fine VCO tuning according to the loaded result of said power-on calibration. The two-step VCO calibration method according to the present invention can cover all the variation of process and temperature and gain the advantages of shorter calibration time, smaller gain of VCO, pretty smaller size of passive loop filter and less operating power consumption.
