| ABSTRACT:In this paper, we introduces the characteristics of medical physiological signal, according to their characteristics, we
design acquisition circuit for medical physiological signal. This physiological signal acquisition system circuit was designed and
implemented based on the 16-bit high-precision serial A/D conversion chip ADS8332, and used 32-bit Cortex-M3 core-based
microcontroller STM32F103RD as the acquisition control chip. This system circuit could achieve up to 16-channels of analog
physiological signals acquisition capabilities. This circuit is designed to fully utilize the ADS8332 high-precision, low-power, high
sampling rate characteristics as well as on-chip integration features, witha signal conditioning circuit and the corresponding anti-jamming
measures to ensure the accuracy of medical physiological signal acquisition and system stability. |
