摘要

一般来说，非分段式 DAC 的 DEM 很好理解，关于这一主题及其基本原理的文献有很多。在分段式 DAC 的背景下，DEM 是一个更令人费解的课题，因为随机化 DAC 的失配引起的误差并不简单，这些 DAC 的元素在名义上大小不一。在本文中，我们将通过逐步推导一个简单的 DAC 架构来探讨分段 DEM DAC 的主题。

Understanding High-Resolution Dynamic Element Matching DACs [Feature]

DEM in the context of non-segmented DACs is well understood in general, and numerous articles can be found in the literature on this topic and its fundamentals. DEM in the context of segmented DACs is a more puzzling subject, as randomizing the mismatch-induced error of a DAC whose elements are nominally different in size is not straightforward. In this article, we cover the topic of segmented DEM DACs via the step-bystep derivation of a simple DAC architecture that is linear by virtue of its shuffling scheme.

期刊介绍： The IEEE Circuits and Systems Magazine covers the subject areas represented by the Society's transactions, including: analog, passive, switch capacitor, and digital filters; electronic circuits, networks, graph theory, and RF communication circuits; system theory; discrete, IC, and VLSI circuit design; multidimensional circuits and systems; large-scale systems and power networks; nonlinear circuits and systems, wavelets, filter banks, and applications; neural networks; and signal processing. Content also covers the areas represented by the Society technical committees: analog signal processing, cellular neural networks and array computing, circuits and systems for communications, computer-aided network design, digital signal processing, multimedia systems and applications, neural systems and applications, nonlinear circuits and systems, power systems and power electronics and circuits, sensors and micromaching, visual signal processing and communication, and VLSI systems and applications. Lastly, the magazine covers the interests represented by the widespread conference activity of the IEEE Circuits and Systems Society. In addition to the technical articles, the magazine also covers Society administrative activities, as for instance the meetings of the Board of Governors, Society People, as for instance the stories of award winners-fellows, medalists, and so forth, and Places reached by the Society, including readable reports from the Society's conferences around the world.
