发明名称 Frequency offset correction method for phase-locked loop circuit provides compensation voltage for frequency difference between controlled oscillator frequency and required frequency
摘要 The frequency offset correction method uses an integrated frequency offset compensation circuit, for providing a voltage which compensates the difference between the output frequency (FO) of the controlled oscillator (CO) of the phase-locked loop circuit and a required frequency (FCL), by comparing the output signal (USF) of the loop filter (SF) at the output of the phase detector (PD) with a reference voltage (UREF). A control stage (ST) supplies a compensation signal (UF) to the controlled oscillator in dependence on the difference between the compared signals. An Independent claim for a phase-locked loop circuit is also included.
