Very Large Scale Integration of Josephson-Junction-Based Superconductor Random Access Memories
Vasili K. Semenov, Yuri A. Polyakov, Sergey K. Tolpygo
Arrays of Vortex Transitional (VT) memory cells with functional density up to have been designed, fabricated, and successfully demonstrated. This progress is due to r…
Ring Oscillators for Clocking Reversible Superconducting Circuits and Fabrication Process Benchmarking
Vasili K. Semenov, Yuri A. Polyakov, Sergey K. Tolpygo
Existing concepts of reversible superconducting circuits as well as demonstrated adiabatic circuits require three-phase bias/clock signals generated by room temperature sources. A…
AC-Biased Shift Registers as Fabrication Process Benchmark Circuits and Flux Trapping Diagnostic Tool
Vasili K. Semenov, Yuri A. Polyakov, Sergey K. Tolpygo
We develop an ac-biased shift register introduced in our previous work (V.K. Semenov et al., IEEE Trans. Appl. Supercond., vol. 25, no. 3, 1301507, June 2015) into a benchmark circ…
New AC-Powered SFQ Digital Circuits
Vasili K. Semenov, Yuri A. Polyakov, Sergey K. Tolpygo
Recent progress of Reciprocal Quantum Logic (RQL) has renewed interest in AC powering of superconductor digital circuits, which had been abandoned since the famous IBM project of 1…
Design and testing of high-speed interconnects for Superconducting multi-chip modules
S. Narayana, V. K. Semenov, Y. A. Polyakov +2
Superconducting single flux quantum (SFQ) circuits can process information at extremely high speeds, in the range of hundreds of GHz. SFQ circuits are based on Josephson junction c…
