A fully integrated capacitance boosting offset calibration circuit for capacitive pressure sensor
2016 International Symposium on Integrated Circuits (ISIC), 2016A novel fully integrated capacitance boosting offset calibration circuit (OCC) for capacitive pressure sensor is presented. With the miniaturization of pressure sensor dimensions, the sensor sensitivity is reduced accordingly to sub-fF/mmHg range. Therefore the analog-frontend (AFE) in the sensor readout circuit has to provide very high gain to meet ...

A simple analog front-end circuit for grounded capacitive sensors with offset capacitance
2013 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2013This paper presents a simple but efficient analog front-end circuit suitable for grounded capacitive sensors. Most of the practical capacitive sensors have an offset capacitance in parallel with a variable capacitance that varies with the quantity being sensed. In some applications, value of offset capacitance can be very large compared to the variable

A circuit for the temperature compensation of capacitive sensors
1996 IEEE International Symposium on Circuits and Systems. Circuits and Systems Connecting the World. ISCAS 96, 2002A voltage reference which yields a voltage proportional to a reference voltage (V/sub REF/) and relative temperature (/spl Delta/T) is presented. The application, typically the interfacing of sensors whose output signal is proportional to V/sub REF/, is described.

The Circuit Elements of Capacitance and Inductance
1973The networks discussed previously have consisted of energy sources and energy dissipators but not energy storers. The circuit elements which store energy endow a network with non-instantaneous properties by virtue of the time necessary for them to increase or decrease their stored energy.

Equivalent Capacitances of Microstrip Open Circuits
IEEE Transactions on Microwave Theory and Techniques, 1972The integral equations that describe the charge distribution near an open-circuited microstrip end are formulated and subsequently solved by a projective method. The solution hinges on development of computationally efficient techniques for dealing with the singularities that occur by special quadrature formulas.
