  1. Adopting a Better Bioimpedance Analog Front End for Next-Generation Vital Signs Monitoring Devices
    Analog Dialogue

    Yi Xin

    This article introduces the basic concepts, application scenarios, and current pain points of bioimpedance measurement. A new measurement solution is also introduced in this article, and the analog front end (AFE) used in the solution supports outputting sinusoidal sweep stimulus and quadrature demodulation, thereby improving the accuracy and convenience of bioimpedance measurement.
