Abstract
A digital phase locked loop has a digitally controlled oscillator for generating an output frequency, a phase detector device for detecting the phase difference between a reference frequency and an output frequency of the oscillator. The phase detector device contains a delta-sigma frequency decision maker, and a digital loop filter, connected downstream of the phase detector device, for actuating the digitally controlled oscillator.
