Profile
Innovative measurement electronics for demanding metrological tasks are developed and made accessible to a wide range of users through subsequent technology transfer. The aim of these developments is to reduce the measurement uncertainty through improved electronic circuits and concepts - especially in the field of amplifier technology. Examples for completed work are a measuring bridge involving a cryogenic current comparator (CCC) and a chopper amplifier for highly accurate resistance calibration or the "Ultrastable Low-noise Current Amplifier" (ULCA) for traceable measurement or generation of direct currents in the range from sub-femtoampere to microampere. Currently, research work in the field of noise thermometry is being carried out. In addition, the working groups 7.61 to 7.63 support the design and operation of Superconducting Quantum Interference Devices (SQUIDs) and their readout electronics. Furthermore, consulting in the field of electrical metrology is offered.
