Hannes Toepfer was born in 1962. He studied Electrical Engineering at the Institute of Technology Ilmenau. From 1991-2002 he worked as a scientific assistant at the Ilmenau University of Technology. In 1996, he gained the Dr.-Ing. (equiv. PhD) with a thesis on the design of magnetic-field sensors (SQUIDs) and in 2003 the habilitation degree with a work on superconductive digital electronics (RSFQ). In 2002 he joined the Institute for Microelectronic and Mechatronic Systems (IMMS gGmbH) where he has been heading the System Design department with a research focus on embedded systems and sensor networks. From 2009 on, he is a Full Professor at Technische Universität Ilmenau and heading the Advanced Electromagnetics Group with a research focus on modeling / simulation and design of superconductive sensors and circuits. He is a senior member of the IEEE.

Design and Development of Superconductive Digital and Mixed-Signal Circuits

Abstract: This contribution describes how superconductive digital electronics can be used to improve the usability of superconductive sensors and detectors. As a result, the outstanding sensitivity of such devices becomes available at a system level. Besides introducing the physical-technical background of the phenomenon, the research issues are described. Results are explained and illustrated.
