A novel interface architecture for differential capacitive sensors [PDF]
2023 9th International Workshop on Advances in Sensors and Interfaces (IWASI), 2023 In this work, we propose an analog fully differential interface for capacitive sensors. The working principle of the proposed solution is based on an autobalancing bridge topology entirely formed by capacitive components. In particular, two capacitors form the sensor, while other components are voltage-controlled capacitors (VCCs) which in steady-state

Digital Converter for Differential Capacitive Sensors
2006 IEEE Instrumentation and Measurement Technology Conference Proceedings, 2006A capacitance to digital converter that directly translates the changes in a differential type capacitive sensor to a proportional digital value is described in this work. The proposed method employs a suitably modified, dual-slope, analog to digital conversion technique.

Digital Converter for Differential Capacitive Sensors
IEEE Transactions on Instrumentation and Measurement, 2008A digital converter that directly translates variations in the capacitances of a differential-type capacitive sensor to a proportional digital value is described in this paper. A conventional dual-slope, analog-to-digital converter is suitably modified to obtain direct capacitance-to-digital conversion (CDC).

A high-accuracy differential-capacitance-to-time converter for capacitive sensors
2015 IEEE 58th International Midwest Symposium on Circuits and Systems (MWSCAS), 2015A high-accuracy switched-capacitor (SC) differential-capacitance-to-time converter (DCTC) for capacitive sensors is presented for high-accuracy ratiometric operation. This circuit does not require component matching. Performances of the proposed circuit are simulated by HSPICE using 0.18 µm CMOS process parameters.

Contamination insensitive differential capacitive pressure sensors
Proceedings IEEE Thirteenth Annual International Conference on Micro Electro Mechanical Systems (Cat. No.00CH36308), 2000In this paper, a contamination-insensitive differential capacitive pressure sensor with a sealed gap is presented. This device is made of three polysilicon layers including a stationary middle plate and the top and bottom plates that are rigidly coupled together by a series of posts hence deflecting in tandem by a change in differential or gauge ...
