A power and area efficient sensor interface consumes 6.5 mW from 1.2 V supplies while occupying 5 mm × 5 mm in 0.13 µm CMOS. The interface enables full bandwidth access to 96 channels of data acquired from cortical microelectrodes as part of a head-mounted wireless recording system for unconstrained primate neuroscience experiments. Open loop amplification and switched-capacitor (SC) filtering with 2.2 µVrms input referred noise conditions the signals before conversion by 10-bit SAR ADCs with… CONTINUE READING
