Abstract
Methods and systems are provided for calibrating voltage-controlled oscillators (VCOs). frequency control information, relating to output frequency of a VCO, which varies based on changes in operational conditions, may be determined. The frequency control information enables indicating the output frequency within a range of allowable values for control inputs and a range of expected values based on the operational conditions. For each control input setting, calibration control information for a calibration voltage associated with a control input, may be determined, based on the frequency control information, with respect to the operational conditions, to generate a constant output frequency. The operational conditions may be assessed, and a calibration voltage corresponding to the assessed operational conditions may be determined. The calibration voltage may be applied, and based on applying the calibration voltage, a tuning control input for tuning the constant output frequency may be determined and applied to the VCO.
