| Abstract: | The design of the signal collection circuit in portable electriccardiogram(ECG)monitor system was described in this paper.The signal collection circuit had the function of collecting electriccardiogram and detecting R waves.The characteristics of the circuit showed in the merits of low noise,less excursion and high common mode rejection ratio(CMRR)because of adopting AD620 as the major component of the amplifiers,but also had the advantage of low cost,small volume and being easy to operation. |
