摘要
本文介绍了一种便携式心电监护系统中信号采集电路的设计。该信号采集电路具有采集心电信号和检测R波等功能。采用AD620作为放大器核心元件,使系统具有低噪音、低漂移和高信噪比等优点,而且成本低廉,体积小,使用方便。
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.
