Abstract
A method of controlling a frequency-modulated oscillatorof a phase-locked loop circuitis described, wherein the oscillatorcomprises a bank of capacitors. The method comprises the steps of (i) switching a capacitorof the bank of capacitorsto change an output frequencyof an output signalof the oscillatorfrom a first frequencyto a second frequency, (ii) determining a frequency information associated with the capacitorand based on at least one of the first frequencyand the second frequency; and (iii) writing the frequency information to a look-up tablestored in a control unitof the oscillator. A corresponding frequency-modulated oscillatorand phase-locked loop circuitare also described.
