摘要：
Following the established two-stage conception for the realization of the ultrastable low-noise current amplifier, new variants have been tailored to meet the special requirements of demanding applications. Changes include new components selected according to stability criteria and new design parameters. For most of these variants, calibration capabilities based on a cryogenic current comparator setup have been developed. The overview given in this contribution will focus on aspects of the achievable measurement uncertainty.
