便携式医疗监护系统中信号调理模块的设计

Signal Adjustive Module of Portable Medical Monitoring System

从微功耗、微型化设计的角度出发,结合便携式医疗监护系统的总体设计思路和系统中信号调理模块的设计要求,详细阐述了信号放大电路、滤波电路等的设计思路和具体实现方法。该方法能较好地实现人体生理微小信号的不失真放大,为便携式系统提供了较高精度信号调理模块的解决方案。

Combining with the overall design method of portable medical monitoring system and the design requirement of the signal adjustive module,the article elaborated the design scheme and implementation strategy of the signal amplifier circuit and filter circuit from the point of view of micropower and micromation in detail,which could amplify the tiny physiological signal of human body undistortedly and provided the design scheme of high precision signal adjustive module in portable system.
