摘要
低噪声心电放大器的设计是生物医学电子学研究课题之一,是对心电信息进行数据采集与处理的重要环节。为此,本文根据线性迭加原理,采用集成运放构成的电路来降低本机噪声。用这种方法研制成的心电放大器无需对元器件(低噪声集成运放)进行严格挑选,而能得到最佳性能。
The design of a low noise electrocardiosignal amplifier, as a research subject of biomedical electronics, is a key link in data acquisition and processing of electrocardiosignal. For this reason, this paper put forward a new method based on linear superposed principle that the local noise can be suppressed in a circuit structure consisted of integrated operational amplifiers. The electrocardiosignal amplifier made from the new method mentioned above need not proceed a strict selection in the element device (low noise integrated operation), and will gct the optimal performance.
