We designed a novel biopotential amplifier, which can restrain electrode offset and baseline drift effectively in a single stage. Still it keep the characteristics of high input impendance, low noise , high gains and high CMRR .

• 我们设计了一款具有电极失调及基线漂移抑制作用的单级心电信号前置放大器,该放大器既能够有效抑制直流电极失调和基线漂移,又保持了高输入阻抗,低噪声、高增益和高共模抑制比等特点。
