REDUCTION OF THE SETTLING TIME AND COMPENSATION OF PHASE ERRORS OF FREQUENCY SYNTHESIZERS BASED ON PHASE-LOCKING LOOPS

摘要

The invention relates to a device and a method for generating an alternating quantity, especially by means of a frequency synthesizer comprising a phase-locking loop, in order to create a frequency curve and a phase angle. The inventive device and method are characterized by a control unit (8) for modulating and interfering with input signals fed into the phase-locking loop, a phase detector (7) for detecting the change in the leading edge regarding the input signals in accordance with the interferences, and an apparatus for compensating phase errors according to the detection.
