DOI: 10.1109/tbcas.2021.3131642
Abstract: A multi-channel, CMOS-based biopotential acquisition system is presented that uses amplitude modulated, frequency division multiplexing (AM-FDM) to decrease wire count and provide resilience against motion artifacts and cable noise. Differential active electrode (AE) pairs capture… read more here.

DOI: 10.1109/tcsii.2022.3176272
Abstract: This brief reviews the principle and design of dynamic range (DR) enhancement techniques for artifact-tolerant biopotential-acquisition ICs. In order to record small input signals without being disturbed by large artifacts, which may arise from motion… read more here.
