Abstract

A 1 GΩ star-mesh quantized Hall array resistance standard (QHARS) made of thirty-seven quantum Hall effect (QHE) elements was fabricated and tested. The 1 GΩ QHARS has three orders of magnitude fewer QHE elements than a largely series 1 GΩ QHARS, which would require approximately 77,480 QHE elements. A dual source bridge, using a nanovolt detector and modified algorithm using least-squares analysis to extrapolate a bridge null from five points near null of the linear measurement system. The 1 GΩ star-mesh QHARS was used as a standard to calibrate 100 MΩ, 1 GΩ, and 10 GΩ high resistance standards. The star-mesh measurements agreed within the combined standard uncertainties of the values of these standards based on traditional high resistance scaling from the i = 2 quantized Hall resistance value of 12 906.403 7 ... Ω, where guarded Hamon transfer standards and dual source bridges are used to build-up to high resistance ranges from 1 MΩ standard resistors.
