A 16-channel TDM analog front-end with enhanced system CMRR for wearable dry EEG recording

This paper presents a 16-channel analog front-end (AFE) for wearable dry EEG recording. A novel AFE architecture that combines time division multiplexing (TDM) and chopping stabilization (CS) to improve the system common mode rejection ratio (CMRR) and the input-referred noise is proposed. With TDM, the reference electrode is connected to single channel… CONTINUE READING
