Abstract
A method of controlling a frequency-modulated oscillator 110 of a phase-locked loop circuit 100 is described, wherein the oscillator 110 comprises a bank of capacitors 413. The method comprises the steps of (i) switching a capacitor 414 of the bank of capacitors 413 to change an output frequency 1050 of an output signal 112 of the oscillator 110 from a first frequency 1051 to a second frequency 1052, (ii) determining a frequency information associated with the capacitor 414 and based on at least one of the first frequency 1051 and the second frequency 1052; and (iii) writing the frequency information to a look-up table 224, 225, 226 stored in a control unit 120 of the oscillator 110. A corresponding frequency-modulated oscillator 110 and phase-locked loop circuit 100 are also described.
