PHASE-CONTROL CIRCUIT ARRANGEMENT AND METHOD FOR OPERATING SAID CIRCUIT ARRANGEMENT

摘要

The inventive phase-control circuit arrangement comprises a phase-control circuit (PLL) for producing a controlled frequency (FVCO), provided with a control input and a control circuit output. The frequency can be picked off from the control circuit output. A frequency meter (51) is connected to the control circuit output of the phase control circuit (PLL) in order to measure the frequency (FVCO). A calculating unit (53) is also provided in order to determine the steepness (KVCO) according to the measured frequency and to obtain a correction value (K) therefrom and is connected on the output side to the control input (4,3).
