| 摘要 |
The invention relates to a radio-frequency circuit comprising:—a control unit; and—a phase-locked loop; wherein the control unit is arranged to determine an offset between an actual value of a reference frequency at the input to the loop on the basis of a measurement of the signal output from the filter of the loop, and a theoretical value of said frequency known to the control unit, via a relation known to the control unit, and to control a correction of said offset. |
