摘　　要：多通道的生物电放大器不仅必须具备单通道生物电放大器所具备的特点 ,还须结构简单 ,调试容易 .介绍两种结构简单又性能优良的生物电放大器 。WT5”BZ]The Multi Channel Bio amplifier has been widely used in many biomedical instruments,such as EEG and body surface ECG.To detect weak bio signals under strong interference,the Multi channel Bio amplifier must have the characters of high input impedance and high CMRR.Meanwhile they mut be simple to match the small dimension of the instrument.Two kinds of novel multi channel bio amplifiers are presented in this paper.They are extremely simple but perform well in the application of ECG measurement.
