摘要：

Capacitance　measure　is　a　technique　for　applications　such　as　capacitance　tomography　and　capacitive　sensor　readout.　This　paper　presents　a　multiple　channel　capacitance　measurement　IC　which　is　based　on　a　switched-capacitor　design　in　0.18um　process.　It　can　be　used　on　electronic-skin　or　other　array-Type　sensors　system.　It　contains　of　capacitance　voltage　conversion　units　and　a　single-slope　ADC.　It　uses　multiple　channels　at　the　same　time　to　compensate　the　disadvantage　on　speed.　Test　result　shows　that　the　dynamic　range　can　reach　45.1dB,　and　the　conversion　rate　is　about　5us/row　in　this　paper.　©　2018　IEEE.
