MODELLING THE DIGITAL-TO-ANALOG FREQUENCY CONVERTER IN THE VERNIER FEEDBACK PATH OF SELF-OFFSET PHASE-LOCKED LOOP WITH MULTIPLICATION
Annotation
One of solutions to the problem of improvement of spectral composition of output oscillation of selfoffset phase-locked loop with multiplication implies a variation in feedback path structure. The Vernier feedback path makes it possible to diminish significantly the phase noise level in the self-offset phaselocked loop pass band (in the vicinity of carrying oscillation) while maintaining the specified loop multiplication factor. Analysis of noise filtering is carried out, and modelling in Fastmean 6 environment is performed for digital-to-analog frequency converter in the Vernier feedback path. The resulting oscillations spectra are presented. Recommendations on the method applications are formulated.
