Superconducting integrated circuits (ICs) based on Josephson junctions (JJs) and
superconducting materials subvert semiconductor ICs at the device level. For over 50 years …

We present measurements of the self-and mutual inductance of NbN and NbN/Nb bilayer
inductors (microstrips, striplines, serpentines, etc.) with Nb ground plane (s) fabricated in an …

Arithmetic Logic Unit (ALU) is an integral part of digital signal processing applications and
computing systems. We used ALU, based on Kogge-Stone adder, as a reference circuit to …

A pseudorandom binary sequence of 7-bit word length (PRBS-7) generator has been
designed as a low complexity circuit to validate the dual RSFQ/ERSFQ standard cell library …

The Energy-efficient Rapid Single Flux Quantum (ERSFQ) logic family offers zero-static
power dissipation. Any ERSFQ circuit requires a feeding Josephson transmission line …

There has been renewed interest and efforts in increasing the complexity of superconductor
circuits by means of electronic design automation (EDA). Serial biasing (SB) is a technique …

Superconductor single-flux-quantum (SFQ) logic family has been recognized as a promising
technology for cryogenic applications (eg, quantum computing, astronomy, metrology) …

Single-Flux Quantum (SFQ) digital logic is typically both energy efficient and fast, but the
logic that uses reversibility provides the most extreme method for improving efficiency. We …

Energy-efficient rapid single flux quantum (ERSFQ) devices have unique energy
advantages with a power consumption of less than 0.001 fJ per single-bit switch, even …

ERSFQ circuits eliminate the dominant portion of static power consumption in RSFQ circuits
by using current-limiting Josephson junctions and inductors instead of bias resistors. In …
