  • Abstract
    A new resistance comparison bridge is being built at LNE to ensure the ohm traceability in terms of the quantum Hall effect (QHE) with a target uncertainty of some parts in 1010. We describe the instrument, the performance of which relies on the development of a couple of versatile and well synchronized current sources, an accurate and stable current divider and a cryogenic current comparator (CCC) having a low noise of 84 pA.t/Hz1/2 .
