ELECTRONIC DEVICE FOR GENERATING A FRACTIONAL FREQUENCY |
摘要 |
<p>It is described an electronic device for generating a fractional synthesized frequency. The device comprises a multi-phase controlled oscillator adapted to generate, from a control signal, a plurality of signals phase-shifted each other and comprises a phase detector adapted to receive a selected signal from the plurality of phase-shifted signals, to receive a reference signal and to measure a difference between a phase of the selected signal and a phase of the reference signal. The electronic device further comprises control means for estimating, from the measured phase difference, a phase error affecting the generation of at least one of the plurality of phase-shifted signals, and for generating a corrected measure of the phase difference taking into account the estimated phase error, the corrected measure being used to provide the control signal.</p> |
