Abstract:

This paper presents the first noncontact electrocardiogram (ECG) recording IC that suppresses the effects of common-mode interference (CMI), motion artifacts, and extra common-mode to differential-mode (CM-DM) conversions induced by the motion artifacts. Implemented in an 8-channel ECG recording with a digitally-assisted time-division multiplexing (TDM) architecture, the IC achieves a total CMRR (TCMRR) of 110dB and an adaptation in response to electrode-tissue impedance (ETI) variations in less than 0. 3s.
