    We analyse a thin-film cryogenic current comparator (CCC) intended to be used in ac measurements. Our analysis shows that 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.
