Abstract
Official abstract text for this publication.
Representative implementations of devices and techniques provide analog to digital conversion of analog inputs. A multistage comparator using a feed-forward technique can provide noise shaping of conversion errors. For example, the comparator may feed a conversion error forward from a first stage to a next stage of the multistage comparator.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus, comprising: a first stage arranged to receive an analog input and to perform a first conversion based on the analog input; a delay component arranged to receive and delay a conversion error of the first conversion, based on a predetermined delay; a combiner arranged to receive an output of the first stage and to combine the output with the error to form an input of a next stage; and a next stage arranged to receive the output of the first…
