Device for measuring capacitance

Measurement Techniques, 1995
A description is given of a device for measuring the capacitance of capacitative transducers. The measuring circuit uses a nonlinear twin-T four-terminal network in a pulse width balancing regime. An expression is obtained for the transfer function of the device, and the results of experimental studies are given.

Gate Capacitance Measurement Using a Self-Differential Charge-Based Capacitance Measurement Method

IEEE Electron Device Letters, 2015
In this letter, we propose a self-differential charge-based capacitance measurement(SDCBCM) method. It is specifically applied to measure MOSFET gate capacitance with high accuracy. SDCBCM has two main advantages. First, it employs a newly proposed self-differential method to derive the capacitance-voltage ( $C$ – $V$ ) curve of gate ...

Direct Measurement of Capacitance

IETE Journal of Research, 1976
A method of measurement of capacitance is described wherein the unknown capacitance can be directly read. Measurements are done using 1 MHz stable crystal controlled oscillator. A two stage amplifier is used to amplify the low level signal before it is rectified and displayed.

Capacitance measuring circuit for water waves

Review of Scientific Instruments, 1979
A simple, reliable, integrated circuit is described which is used to measure standing water waves of amplitudes ranging from less than 1 mm. The circuit has a high dynamic range and is linear for changes in water depth of several centimeters. The sensitivity of this capacitance measuring device is 38 mV/mm of wave amplitude, enabling small amplitude ...

Automatic Capacitance Measuring System

1971
Abstract : The report describes the development of an automatic capacitance measurement system. The system was specifically designed to be compatible with a capacitive strain gage working in ambient temperatures up to 1500F. The progression of the development yielded a system capable of measuring three terminal capacitors at a distance of up to 150 ...

Capacitive measurement system for liquid level measurement

2016 5th International Conference on Computer Science and Network Technology (ICCSNT), 2016
There are many types of liquid level measurement instrumentations in modern technology, including the multiple-liquid level measurement. However, there are some practical considerations that make them unfit to use in car washer tanks. They are often too expensive, too cumbersome, too awkward and unsuitable in tanks.

Measurement of small capacitances using phase measurement

[1990] Proceedings. The Twenty-Second Southeastern Symposium on System Theory, 2002
A method for measuring small capacitance values without expensive test setups is presented. This method utilizes phase measurement with standard laboratory equipment. In the process of measuring the capacitance, the loss factor of the capacitance is also determined.

Synaptic exocytosis and endocytosis: capacitance measurements

Current Opinion in Neurobiology, 1996
Exo- and endocytosis are accompanied by changes in membrane capacitance. Capacitance measurements in synaptic terminals have proven recently to be a useful adjunct to other techniques in examining presynaptic mechanisms. New information has emerged from these studies about the size and dynamics of synaptic vesicle pools, about the Ca2+ dependence of ...
