ECG amplifier

The development of ECG preamplifier and calibrating signal circuit;

心电放大器前置放大级及定标电路设计

The design of Electrocardiogram Amplifier (ECG) is mainly consisted of a preamplifier and a band-pass filter, which is made up of four BiFET LF411 operational amplifiers, some resistances and capacitances.

以BiFET LF411型运放构成的前置放大器和以有源高通-低通滤波器为主要部件的高性能心电放大器可实现输出电压高增益、低噪声、高灵敏度,保证心电信号清晰稳定,满足临床监护以及病理分析的要求。
