Abstract
An illustrative biopotential measurement system includes a plurality of electrodes each configured to record a different signal included in a plurality of signals representative of electrical activity of a target within a user; a plurality of non-inverting operational amplifier circuits each connected to a different electrode included in the plurality of electrodes and each configured to output a different amplified signal included in a plurality of amplified signals representative of amplified versions of the plurality of signals; and a common-mode feedback circuit configured to measure a common-mode signal between the plurality of amplified signals and provide the common-mode signal to the non-inverting operational amplifier circuits. The non-inverting operational amplifier circuits are configured to use the common-mode signal to generate voltage-divided feedback signals used to generate the plurality of amplified signals.
