TL;DR: In this article, a method and a device for digital/analog conversion are proposed, whereby for improved use of a dynamic element matching algorithm, in particular a data weighted averaging algorithm, the number of existing conversion elements is greater than a maximum number of possible input or control codes for the conversion elements, which would actually be necessary for a maximum value of the digital word to be converted in each case.

Andreas Wiesbauer,Martin Clara,Antonio Di Giandomenico,Luis Hernandez,Susana Paton +4 more
- 06 Feb 2004
TL;DR: In this paper, a loop filter for a continuous time sigma delta analog to digital converter which converts an analog input signal into a digital output signal was proposed, consisting of an active analog filter which includes active devices for providing a power gain, wherein the number of active devices is lower than the filter order of the active analogue filter.
