The various implementations described herein include techniques and apparatuses for multi-channel biopotential signal acquisition, biopotential signal pre-processing, and adaptive signal conditioning. In one aspect, an apparatus is provided for adaptive signal conditioning for biopotential acquisition. The apparatus includes an analog circuit configured to amplify biopotential signals, and a mixed-signal circuit (e.g., which can include an adaptive digital algorithm) coupled to the analog circuit and configured to suppress aggressor signals such as baseline wandering signals and power-line-induced noise in the biopotential signals before amplification of the biopotential signals.
