Abstract
We analyze a thin-film cryogenic current comparator (CCC)
intended to be used in ac measurements. Our analysis
shows that by calibrating the dc ratio error of the
thin-film CCC against a conventional CCC, it can be used
up to 10 kHz as a sensitive and highly accurate current
comparator. We have fabricated a practical 1:1 planar CCC
integrated with a low-noise SQUID magnetometer. The
preliminary experiments obtained from the 1:1 comparator
are described.
