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.

A capacitance level sensor design and sensor signal enhancement

2011 6th IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2011
This paper introduces a novel fringe field capacitive sensor. To enhance the sensor signal, various sensor electrode design strategies and a surface modification method are introduced, discussed and compared. The sensors are characterized by both simulations and experiments.

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).
