A low power biopotential amplifier in 0.35um CMOS for portable EEG signal amplification

In this paper, a low power differential biopotential amplifier (BPA) targeted for front-end electroencephalogram (EEG) signal amplification is reported. The proposed BPA is chopper stabilized to minimize flicker noise or 1/f noise, improving the fidelity of the signal measurement. This work aims to...
