  • Analog Front-End Design for ECG Systems Using Delta-Sigma ADCs (Rev. A)
    PDF, 191 Kb, Revisión: A, Archivo publicado: abr 13, 2010
    This document discusses the characteristics of electrocardiogram (ECG) signals and different front-endapproaches for ECG signal acquisition. The tradeoffs between different approaches and the effects on overall system design are discussed. The report also includes descriptions of potential implementations of the front-end architecture using the ADS1258 and ADS1278 and respective noise measuremen
