Description
Summary:A novel four-terminal pair impedance bridge combined with a quantum Hall resistor will be presented. The impedance bridge is based on pulse-driven Josephson arrays. A very simple setup is possible due to the triple-series connection of the quantum Hall resistor that renders combining networks superfluous. This combination of the two well-known macroscopic quantum effects presents a unique possibility for the realization of electrical units. Moreover, the Josephson bridge can be used to precisely investigate the plateau shape of quantum Hall devices in the AC regime.
