摘要

本文提出了一种适合于心电采集的由放大器组成的模拟前端。它采用180nm CMOS SCL技术设计，采用Cadence Virtuoso环境，1.8V电源。心电监护装置由保护电路、模拟前端前置放大器、缓冲器、低通滤波器和主放大器组成。保护电路用于防止心电图中电极之间、除颤器使用期间或静电放电(ESD)事件产生的电压浪涌。心电信号分级放大、仪表放大和主放大。低通滤波器用于降噪，缓冲器用于心电前端两级阻抗匹配。

ECG Monitoring System using180nm Technology

This paper present analog front end comprising amplifier suitable for ECG acquisition. It is designed using 180nm CMOS SCL technology using Cadence Virtuoso environment with 1.8V power supply. ECG monitoring setup consists of protection circuit, an analog front end pre-amplifier, buffer, low pass filter and main amplifier. Protection circuit is used for protection from voltage surges which can occur between electrodes in electrocardiogram, during the application of defibrillator or due to electrostatic discharge (ESD) event. The ECG signal is amplified in stages, instrumentation amplifier and main amplifier. Low pass filter is designed for noise cancellation and buffer is used for impedance matching between two stages of ECG front end.
