Abstract :
A quantized Hall resistance (QHR)-based capacitance measurement chain has been developed. The chain comprises an AC resistance bridge together with an AC-DC calculable resistor, a multifrequency quadrature bridge, and a capacitance bridge. The use of the multifrequency quadrature bridge enables the measurement of the frequency dependence of capacitors in the range between 1-1.592 kHz. The results demonstrate that the frequency dependence of 10-pF standard capacitors can be measured based on the QHR with a relative standard uncertainty of 3×10-8
