Journal ArticleDOI
Three-dimensional multi-terminal superconductive integrated circuit inductance extraction
TL;DR: In this article, the authors proposed InductEx, an extraction program based on the three-dimensional calculation software FastHenry, which uses segmentation techniques designed to accurately model the geometries of superconductive integrated circuit structures.
Journal ArticleDOI
Orthogonal sequencing multiplexer for superconducting nanowire single-photon detectors with RSFQ electronics readout circuit
Matthias Hofherr,O. Wetzstein,S. Engert,Thomas Ortlepp,B. Berg,Konstantin Ilin,D. Henrich,Ronny Stolz,Hannes Toepfer,Hans-Georg Meyer,Michael Siegel +10 more
TL;DR: An efficient multiplexing technique for superconducting nanowire single-photon detectors based on an orthogonal detector bias switching method enabling the extraction of the average count rate of a set of detectors by one readout line is proposed.
Journal ArticleDOI
Reduced Power Consumption in Superconducting Electronics
TL;DR: In this article, the authors present an assessment of different approaches for reducing the static power consumption by investigating the potential of inductive bias distribution networks as well as reduced critical currents and inductive biasing.
Journal ArticleDOI
Experimentally verified inductance extraction and parameter study for superconductive integrated circuit wires crossing ground plane holes
TL;DR: In this article, a fast network extraction method using InductEx, which is a pre-and post-processor for the magnetoquasistatic field solver FastHenry, is used to calculate the inductances of a set of superconducting quantum interference devices with ground plane holes of different sizes.
Journal ArticleDOI
Recent Developments in Superconductor Digital Electronics Technology at FLUXONICS Foundry
J. Kunert,Oliver Brandel,Sven Linzen,O. Wetzstein,Hannes Toepfer,Thomas Ortlepp,Hans-Georg Meyer +6 more
TL;DR: Following the hierarchical cell-based design strategy, a design kit with basic cells is developed and the process is suitable for the integration of complex digital and mixed-signal circuits for smart multichannel superconductor sensor applications with a digital interface.
