该论文提出了一种15通道数字有源电极系统，用于便携式生物电位信号采集。通过将干电极与现场放大结合，解决了传统有源电极需要模拟缓冲器驱动信号的问题，实现了低噪声、高鲁棒性的生物电位测量。
electrodes (AE), i.e., the combination of dry electrodes with in situ amplification, are increasingly used for biopotential measurements in emerging healthcare and lifestyle applications [1]. Compared to gel-based wet electrodes, dry electrodes enable fast set-up time, greater user comfort, and long-term monitoring. AE amplifiers ensure local amplification providing improved robustness to noise interference and cable motion artifacts. However, current AEs have analog outputs requiring powerful analog buffers to drive biopotential signals over measurement cables. Furthermore, analog outputs must be digitized by the back-end (BE) system [2,3]. Besides, parameter mismatch between AEs limits the overall CMRR. CMFB [1] or CMFF [2] helps but comes at
