On the dynamic behavior of a novel digital-only sigma--delta A/D converter

Published: 04 September 2004 Publication History

Abstract

Conventional sigma-delta (ΣΔ) analog-to-digital (Ad) converters are based on an analog ΣΔ modulator followed by a digital filter. In this paper we propose a new architecture of a first-order ΣΔ modulator that needs no active analog components. We call this ΣΔ modulator "digital-only," and implement with it Ad converters in Fpga's or directly in the software of microprocessors. We here discuss aspects of the dynamic behavior of the proposed structure.
