Method And Apparatus For Multi-Band Voltage-Controlled Oscillator (VCO) Band Selection

A method and apparatus select an optimal frequency band of a plurality of frequency bands of a multi-band voltage-controlled oscillator (VCO) to achieve a particular output frequency from the multi-band VCO. The optimal frequency band is selected, automatically, based on performing a one-point calib...

Zusammenfassung:	A method and apparatus select an optimal frequency band of a plurality of frequency bands of a multi-band voltage-controlled oscillator (VCO) to achieve a particular output frequency from the multi-band VCO. The optimal frequency band is selected, automatically, based on performing a one-point calibration phase followed by a multi-point calibration phase. The one-point calibration phase produces an initial frequency band selection and the multi-point calibration phase selects the optimal frequency band from a group of frequency bands including the initial frequency band selection, a higher frequency band consecutively higher in frequency relative to the initial frequency band selection, and a lower frequency band consecutively lower in frequency relative to the initial frequency band selection.
