    摘要: The present invention provides a circuitry of a biopotential acquisition system comprising an input node, an ETI transmitter and an ADC. The input node is coupled to an electrode of the biopotential acquisition system, and the electrode is used to be in contact with a human body. The ETI transmitter is configured to generate a transmitter signal to the input node. The ADC is coupled to the input node, and is configured to process an input signal from the input node to generate a digital signal, wherein each of the input signal and the digital signal comprises components of an ECG signal and an ETI signal.
