An integrated capacitance bridge for high-resolution, wide temperature range quantum capacitance measurements.
We have developed a highly sensitive integrated capacitance bridge for quantum capacitance measurements. Our bridge, based on a GaAs HEMT amplifier, delivers attofarad (aF) resolution using a small AC excitation at or below k(B)T over a broad temperature range (4-300 K). We have achieved a resolution at room temperature of 60 aF/√Hz for a 10 mV ac excitation at 17.5 kHz, with an improved resol...
متن کاملTraceability Chain of the Capacitance Unit to Quantum Hall Effect at Inmetro - Four-terminal Coaxial Bridge
− This paper describes the development of a four-terminal coaxial bridge, part of the traceability chain of the capacitance unit to the quantum Hall effect, in construction at Inmetro. This bridge will also be used to calibrate AC resistance and high-value capacitance standards. Here we describe the final construction stages and preliminary measurements of the four-terminal coaxial bridge. We a...
متن کاملA Capacitance Measurement System Using an IVD Bridge
A new system to characterize the magnitude and phase characteristics of 1 pF to 1 F capacitance standards over the 50 Hz to 100 kHz frequency range is described. The system has been developed to provide measurement support for LCR meters and general impedance measurement services. It consists of an inductive voltage divider (IVD) bridge capable of accurately comparing two capacitance standards...
متن کاملIntegrated in a 13mm Pressure-Sensing System
Small form-factor piezoresistive MEMS sensors, often configured in a Wheatstone bridge, are widely used to measure physical signals such as pressure [1-3], temperature [4], force [1], and gas concentration. A common method to realize a digital output from the bridge involves biasing the bridge with a DC voltage source and using a low-noise amplifier followed by an ADC. While a bridge measuremen...
متن کاملCalibration of Capacitance Standards with a Quadrature Bridge
− National Metrology Institutes employ the quadrature bridge in the traceability chain to derive the farad from the ohm (represented with the quantum Hall effect). The bridge calibrates the capacitance product of the two capacitors being measured; a separate measurement with a ratio bridge is usually required to estimate each capacitor independently. We describe here a method which, by measurin...
