摘要
针对心电信号具有生物电信号的微弱性、易受干扰等特性，本文介绍了一种高性能的放大电路，将差分放大电路、右腿驱动电路、双T型有源带阻滤波器及C8051F020单片机资源综合应用于该设计中，在节省了成本的同时，有效消除各种干扰，使微弱的心电信号得到充分的放大，以利于医学分析与研究。
This paper introduces a high performance amplifier circuit for ECG signal with the faint of biological vulnerability to interference and other features, the differential amplifier circuit, the right leg drive circuit, dual T-active band-stop filter and C8051F020 integrated single-chip resources used in the design. In this way can save cost and eliminating all obstacles to the full weak ECG signal amplification and facilitate medical analysis and research.
