Digital sigma-delta modulator

 Chernyh A.V.
Date of publication

 This paper is intended for acquaintance with digital sigma-delta modulators (SDM), functions which they carry out on an example of the circuit of a fractional divider in a feedback loop of phase-locked loop (PLL). Theoretical calculations of influence of SDM work on quality of a generated signal are resulted and recommendations under SDM block diagram are formulated.
