摘要：

this　paper　presents　a　miniature　front-end　integrated　circuit　for　tactile　sensors.　To　achieve　high　sensing　accuracy　and　density,　a　fast　capacitance-to-voltage　conversion　module　and　an　area　efficient　ADC　module　with　high　resolution　is　designed.　The　front-end　IC　is　implemented　based　on　SMIC　0.18μm　CMOS　process　technology.　Simulation　results　show　that　the　conversion　time　of　the　C-V　converter　is　1.6　μs　and　the　input　range　for　the　circuit　is　from　1　pF　to　4pF.　The　proposed　single-slope　ADC　has　a　12-bit　resolution　and　operates　at　340-MHz　clock　frequency,　with　a　differential　nonlinearity　of-0.09/+0.02　LSB　and　the　integral　nonlinearity　of-0.68/+0.26　LSB.　The　proposed　front-end　IC　shows　the　feasibility　for　the　miniature　tactile　sensors.　©　2019　IEEE.
