Abstract:

MEMS capacitive pressure sensor has the advantages of low power consumption,good temperature stability,solid and fast dynamic response.Five kinds of detection circuit for MEMS capacitive pressure sensor are introduced,which are based on PWM,operational amplifiers,charge injection,FM and AC amplifier respectively.These detection circuits are compared in stability,sensitivity of measurements,resistance to spurious and some other aspects,and their advantages and disadvantages are concluded.This paper provides useful references to designer of detection circuit for MEMS capacitive pressure sensor.

Key words: MEMS;capacitive pressure sensor;detection circuit;advantage and disadvantage
