METHOD FOR RE-CENTERING A VCO, INTEGRATED CIRCUIT AND WIRELESS DEVICE |
| 摘要 |
A method of re-centering a voltage controlled oscillator of a wireless device comprising a phase locked loop circuit is described. The method comprises receiving an input frequency signal at a phase detector of the phase locked loop circuit from a frequency source; generating an oscillator signal based on the received frequency signal; selectably opening a feedback loop of the phase locked loop circuit when in a calibration mode of operation, performing coarse frequency tuning of the oscillator output signal; performing fine frequency tuning of a coarsely adjusted oscillator output signal; and closing the feedback loop. |
