This brief presents a low-power multi-channel analog front-end (AFE) for bio-potential
recording. Time-division-multiplexing (TDM) technique is used to save chip area by sharing …

A multi-channel time-division multiplexing (TDM) analog front end (AFE) with low mismatch
and high input impedance for bio-sensors is proposed. To reduce mismatches among …

Walsh-Hadamard based orthogonal sampling of signals is studied in this paper, and an
application of this technique is presented. Using orthogonal sampling, a single analog-to …
