Abstract :
Mixed signal SoC for ECG waveform acquisition is designed and discussed in this paper. The SoC is a terminal of a special wireless sensor network (WSN) as a data source. Time parameters and communication band width are discussed. Especially, to satisfy the requirements of ECG waveform data acquisition and transmission the relation of sampling rate and communication band width is discussed. Based on the analysis of ECG frequency characteristics and the real time requirements of the WSN, synchronous data acquisition and transmission architecture of the SoC is designed. The DFG (Data flow graphic) model of the architecture is built for time parameters analysis and circuits design as well.
