Fully differential topologies
are well-suited for biopotential amplifiers, mainly for single-supply
battery-powered circuits such as portable wearable devices where a reduced
number of parts is desired. A novel fully differential biopotential amplifier
is proposed with the goal of providing electrode offset rejection, bandwidth
limitation, and a temporal response compliant with biomedical standards with
only a single commercial quad operational amplifier (OA) integrated circuit.
