通过对MEMS电容式加速度计的差分电容检测电路优缺点的比较
结合直流充放电检测方法和交流测量方法的优点
设计了微分检测电路
用方波作为载波。该电路由方波信号发生器、微分电路、全波整流电路和滤波电路组成。经试验验证:可检测到10-16F的差分电容
且其非线性度小于±1%FS
可作为MEMS电容式加速度计的后续处理电路。
In order to detect the MEMS capacitive accelerometer signal
through compared of the advantage and the disadvantage of the difference capacity detection circuit
combined the direct current charge and discharge and alternating current measurement ways
a differential detection circuit is designed.The carrier wave is rectangular wave
the circuit mainly is composed of rectangular wave occurrence circuit
differential circuit
the whole wave commutate circuit and filter circult.Experiment results show the resolution is 10
-16
F
the nonlinearity is less than ±1 %FS
the system can be used to detect the capacity accelerometer.
