And why lower OSR is more sensitive to ELD? Thanks a lot! best, Ken

So effect due to ELD can be alleviated. See pp.213-215 of the following. https://www.amazon.com/gp/reader/0471465852/ref=sib_dp_pt#reader-link BTW, it seems that 2nd edition of this book is published this year. Last edited: May 5, 2016

Hi pancho_hideboo: Thanks a lot! Dose it mean that the feedback signal traces the input signal more rapidly in a DSM with higher OSR, which leads to lower error? best, Ken

Click to expand... No. Narrower width of DAC results smaller quantized noise. See book I refered.
