Abstract

We describe the operation of a cryogenic current comparator (CCC) bridge that attains high current sensitivity while maintaining stability under a range of measurement conditions. Measurements of 100 M(Ohm) standard resistors and cryogenic thin-film resistors have been made at low voltage levels, based directly on a quantized Hall resistance (QHR) standard.
