Abstract: An instrumentation amplifier includes a first amplifier having one input connected to a first input of the instrumentation amplifier, a second amplifier having one input connected to a second input of the instrumentation amplifier, and a feedback network. The feedback network including an active filter having a first low pass filter characteristic with a first cut-off frequency in respect of differential mode signals at the first and second inputs of the instrumentation amplifier, and a second low pass filter characteristic with a second cut-off frequency in respect of common mode signals at the first and second inputs of the instrumentation amplifier. The disclosure also relates to a device for acquiring biopotential signals and a signal amplification method.

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.
