摘要
仔细地介绍了一实用的超低噪声生物电前置放大器。并对几种不同输入联结法进行了对比测试,结果表明:比之单纯追求CMRR,体表“地”电极共模驱动是解决50Hz干扰问题的更有效的方法。
An extra-low noise bioelectro-preamplifier is introduced.The results obtained with everal different input connections are presented and compared.It indicates that the method of common mode potential driving is more effective than that of only seeking high CMMR for solving 5Hz interfeence problem.
