摘要

介绍了一种用于心电测量和预处理的集成电路。该电路由四个独立的宏模块组成:(1)用于心电跟踪的模拟仪表放大器，(2)高性能sigma-delta a /D转换器，(3)用于心电预处理的计算效率高的线性相位数字滤波器，以及(4)用于数字和模拟心电输出的接口。为了使电路面积和功耗足够小，数字模块选择了位串行方法。高质量的模块和多功能的输出功能使该电路在各种心电监测中非常有用。

An integrated sensor interface circuit for ECG measurements

An integrated circuit for ECG measurements and preprocessing is presented. The circuit consists of four independent macro modules: (1) an analog instrumentation amplifier for ECG tracking, (2) a high-performance sigma-delta A/D converter, (3) a computationally efficient linear-phase digital filter for ECG preprocessing, and (4) an interface for digital and analog ECG output. A bit-serial approach has been chosen for digital modules to keep the circuit area and power consumption sufficiently small. The high-quality modules and versatile output facilities make the circuit very useful in all kinds of ECG monitoring.<>
