Experimental Demonstration of Current Dependence Evaluation of Voltage Divider Based on Quantized Hall Resistance Voltage Divider

The National Metrology Institute of Japan has developed a resistive voltage divider (RVD), which is constructed from a series array of quantized Hall resistance (QHR) bars named “QHR voltage divider” fabricated on one chip. In principle, the QHR voltage divider does not need time-consuming bootstrap self-calibration and is not affected by measurement conditions such as ambient temperature and measurement current Therefore the QHR voltage divider is suitable for use as a reference standard for characteristic evaluation of conventional RVDs. In this paper, the evaluation of RVD current dependence based on the QHR voltage is demonstrated.
