  • Abstract
    We present a 6.4 μW electrocorticography (ECoG)/electroencephalography (EEG) processing integrated circuit (EPIC) with 0.4 μVrms noise floor intended for emerging brain-computer interface (BCI) applications. This chip conditions the signal and simultaneously extracts energy in four fully-programmable frequency bands. Functionality is demonstrated by tuning the four bands to important frequency bands used by ECoG/EEG applications: α (8-12Hz), β (18-26Hz), low-γ (30-50Hz) and γ (70-100Hz). Measured results from in-vivo ECoG recording from the primary motor cortex of an awake monkey are presented.
