Abstract
This paper presents a highly reconfigurable analog front-end (AFE) IC supporting multi-modal (bio)signal monitoring. By efficiently reusing core components, the reconfigurable AFE channel occupies an area of 1.1mm 2 while supporting four acquisition modes, i.e. biopotential (ExG), bio-impedance (BioZ), galvanic skin response (GSR) and general purpose analog (GPA). State-of-the-art sensitivity has been achieved at low power by employing both chopping and dynamic element matching (DEM). The reconfigurable AFE channel consumes 36μW maximum from a 1.2 V supply.
