Abstract

A small-size and very low-power portable Electroencephalogram (EEG) acquisition system will not only improve the patients' quality of life but also extend the device applications. This paper presents a 300μW 8-channel EEG readout front-end ASIC for the implementation of portable acquisition systems. Each channel of the ASIC consists of an AC coupled chopped instrumentation amplifier, a spike filter (SF) and a variable gain stage (VGA), and achieves 80 nV/√Hz input referred noise density and 130 dB CMRR at 50 Hz, while consuming 8.5 μA from a single 3V supply. ASIC has been implemented in 0.5 μm CMOS technology, core area measures 3mm by 4mm, and is capable of operating more than 7 months from two AA batteries.
