  • Abstract
    In this paper, an integrated pulse wave velocity (PWV) sensor that adapts ECG and Bio-impedance (BI) method is proposed. PWV is calculated by measuring the time-difference between the signals from ECG sensor on chest and BI sensor on wrist. To gather these two signals without any cumbersome wires over the body, a noise-shaped body-channel communication method using analog frequency modulation is proposed. A prototype chip fabricated in 0.11μm CMOS process consumes 1.25mW at 1.2V supply while occupying 6mm2.
