Özet:

 

In this study the authors introduce an analysis of rms frequency error performance and spurious signals   generated by two-point modulators. The analysis is not limited to a constant delay and magnitude imbalance between   modulation paths but allows frequency-dependent group delay and amplitude variations as well. Moreover, a discrete   time phase frequency detector model is incorporated in Laplace domain analysis that takes into account the sampling   nature of a phase-locked loop  PLL . Using the spectrum of pulse width modulated charge pump pulses, the spurious   signals at the output of the PLL are evaluated. The proposed formulae are tested on a practical setup and quite accurate   results are obtained.
