Abstract: A biopotential signal acquisition system comprising an analog readout unit configured to receive an analog biopotential signal and to extract an analog measured biopotential signal and an analog reference signal, and an ADC unit configured to provide a digital version of the analog measured biopotential signal and the analog reference signal. The system also includes a first digital filter unit comprising a cascaded integrator-comb filter configured to provide a first digital filtered version of the digital measured biopotential signal and the reference signal, and a second digital filter unit configured to calculate a digital motion artifact estimate based on the first digital filtered version signals.

Abstract: A biopotential signal acquisition system including an analogue readout unit configured to receive an analogue biopotential signal, which may be acquired from at least one electrode attached to a body; and to extract an analogue measured biopotential signal and an analogue reference signal. The system also includes an ADC unit configured to provide a digital version of the analogue measured biopotential signal and the analogue reference signal, a digital filter unit configured to calculate a digital motion artifact estimate based on the digital version of the measured biopotential signal and the reference signal. The system further comprises a reference signal processing unit configured to convert the reference signal into a new reference signal being provided to the digital filter unit based on the correlation between the measured biopotential signal and the reference signal.
