Design and analysis of novel dynamic latched comparator with reduced kickback noise for high-speed ADCs
Abstract
A novel dynamic latched comparator with reduced kickback noise for high-speed ADCs is presented. Dynamic latched comparators suffer from kickback noise. Especially the common-mode kickback noise becomes even more critical in applications with asymmetric input. By using common source input transistors and a decoupling mechanism the novel dynamic latched comparator produces much lower common-mode kickback noise, while the differential kickback noise is also significantly reduced. The simulated results show that the proposed comparator not only produces less than one third of the common-mode kickback noise of other typical dynamic latched comparators, but also settles faster.

The dynamic comparator topology of [15] has a low regeneration time constant and reduced kickback noise.
“The dynamic comparator topology of [15] was considered in this work since it presents a low regeneration time constant and, as an additional advantage, a reduced kickback noise.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
