摘要

近年来，双电极ECG设备越来越受欢迎，可以对心血管健康进行舒适和长期的监测。由于在双电极ECG设备中不使用接地电极或偏置电极，电力线耦合对人体产生的共模干扰(CMI)可高达几十伏。如此大的CMI会破坏心电记录，因此心电设备的模拟前端必须不受大CMI的影响。

22.4 A 27.8μW Biopotential Amplifier Tolerant to 30Vpp Common-Mode Interference for Two-Electrode ECG Recording in 0.18μm CMOS

Two-electrode ECG devices have gained popularity in the recent past to enable comfortable and long-term monitoring of cardiovascular health. As a ground or bias electrode is not used in a two-electrode ECG device, common-mode interference (CMI) caused by powerline coupling to the human body can be as large as a few tens of volts. Such a large CMI ruins the ECG recording, and thus the analog front-end of the ECG device must be immune to large CMI.
