    Abstract

    An 8-channel integrated circuit for motion-artifact-resilient EEG recording is reported. The presented IC employs a novel mixed-signal channel architecture capable of real-time motion artifacts detection and removal in the analog domain, making it needless of an ADC and/or digital signal processing. The channel’s detailed design analysis, system-level architecture, circuit-level implementation, and experimental characterization results are presented. The microchip is sized 12 mm2 and is fabricated in a 130nm CMOS technology. Our measurement results show a voltage gain of 48.3dB, a bandwidth of up to 300Hz, rail-to-rail input DC offset tolerance and 41.5dB artifact suppression while consuming 55uW per channel.
