摘要
与电压型或者电流型传感器不同,纯阻型传感器作为无源器件,在采集时需要避免偏置电压和偏置电流对其产生的影响。一些特定医疗传感器的阻值变化往往是微弱且高阻态的,因此,设计了合适的采样电路,以确保采样范围和可采集度。
Unlike voltage type or current type sensors,pure resistance type sensors,as passive devices,need to pay special attention to avoiding the influence of bias voltage and bias current during acquisition.The resistance changes of some specific medical sensors are often weak and high resistance states.Therefore,suitable sampling circuits have been designed to ensure the sampling range and collectability.
