The signals of flexible and carotid artery is one of important information sources in pathological researches. The electrical signals,which are changed from pulse signals by high sensitivity pressure sensor signals is very weak, and it can be displayed, recorded or acquired by the computer only via amplification through 69-70dB . Op-amp A1, A2, A3 constitute the typical data amplifier,and A4 forms proportional amplifier. Op-amp F324,which is high gain and low power consumption is used here.
