  • Improving Common-Mode Rejection Using the Right-Leg Drive Amplifier
    PDF, 297 Kb, Datei veröffentlicht: 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
