Extending the scale of inductance using 1:1 comparator bridge

Krzysztof Musiol, Tadeusz Skubis

Abstract

An idea of using 1:1 comparison for 10:1 and 1:10 impedance transfer is described in the paper. Results of measurements performed for 10:1 transfer of inductance are discussed. The results achieved prove that using 1:1 comparator bridge and applying proposed procedure is possible to transfer unit to the objects of 10 times smaller values with relative uncertainty only a little higher than uncertainty estimated for 1:1 comparison.
