Analysis and Improvement of an Interface Circuit of Capacitive Sensors

WANG Bin,HUANG Xiao-dong,QIN Ming,HUANG Qing-an(Key laboratory of MEMS of Ministry of education, Nanjing 210096, China)  
A new integrated capacitive sensor is introduced briefly. The sensitive capacitance and the interface are integrated into one chip. The interface circuit, which is based on the Schmitt trigger, works as a capacitor-frequency converter. A differential frequency circuit is designed following the oscillator. It can reduce the common-mode distribution. The output frequency displays a large difference from theoretic calculation during testing. The reason for the difference is analyzed. Circuit schematic and parameters are redesigned to realize the integration with a new sensor designed in our laboratory.
