A high-accuracy differential-capacitance-to-time converter for capacitive sensors

2015 IEEE 58th International Midwest Symposium on Circuits and Systems (MWSCAS), 2015
A 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.

A Low-Power Capacitance-to-Voltage Converter For MEMS Capacitive Sensors

2019 31st International Conference on Microelectronics (ICM), 2019
A new low-power capacitance-to-voltage converter (CVC) for MEMS capacitive sensors is presented. The CVC is implemented using a charge transfer technique, based on a current signal. Its mainly composed of a current mirror and a negative feedback system.

Reducing the Effect of Parasitic Capacitance on the Micro-capacitive Humidity Sensor

2019 IEEE 14th International Conference on Nano/Micro Engineered and Molecular Systems (NEMS), 2019
It is the most important issue of how the effects of parasitic capacitance can be reduced during the development of micro-capacitive humidity sensor systems. For this purposes, in this paper, step-by-step optimizations were carried out through packaging and circuit to achieve a high-precision, high-stability, and high-repetition humidity sensor system.

Single-Wafer Pressure Capacitive Sensor

2007 IEEE International Symposium on Circuits and Systems (ISCAS), 2007
A novel manufacturing process for pressure sensor without the need of wafer bonding is presented. Its main advantages are a simple fabrication process and an efficient integr ability with other devices. The sensor is composed of a polysilicon membrane that deflects due to the pressure difference applied over it.

Digital Converter for Differential Capacitive Sensors

IEEE Transactions on Instrumentation and Measurement, 2008
A 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).
