  • Improving Common-Mode Rejection Using the Right-Leg Drive Amplifier
    PDF, 297 Kb, 档案已发布: Jul 6, 2011
    This article discusses the need to improve common-mode rejection (CMR) in electrocardiogram (ECG) subsystem applications. Several different techniques to improve CMR while also considering both patient and operator safety are presented. This report also reviews the implementation of the right-leg drive (RLD) loop technique to improve CMR using the ADS129x family of analog-to-digital converters (in
  • Analog Front-End Design for ECG Systems Using Delta-Sigma ADCs (Rev. A)
    PDF, 191 Kb, 修订版: A, 档案已发布: Apr 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
