A 160μA biopotential acquisition ASIC with fully integrated IA and motion-artifact suppression

Abstract

There exists a growing interest in wearable/portable biopotential monitoring systems. These systems have very strict requirements in terms of power dissipation, high signal quality, small area (minimal use of externals) and robust operation during ambulatory use. The latter is emerging as an especially important problem since in real-life ambulatory conditions, motion artifacts can disturb and potentially saturate the readout channel. In addition, requirements for multimodal information acquisition require even more functionality with minimal power dissipation.
