Peculiarities of RSFQ Applications with High-Tc Superconductors - an Approach for Design

The significant progress in the development of Rapid Single Flux Quantum (RSFQ) logic circuits indicates their potential for fast cryoelectronic device applications. The possibilities of realizing logic components based on this principle with high-T, superconductive (HTS) materials have been studied by means of numerical computations. The most crucial task is to manage the trade-off between desired high critical currents and the loop inductances, which can not be made arbitrarily small. Parameter extractions for typical layout arrangements and dynamical simulations including thermal noise give justification for expecting small scale HTS-RSFQ implementations.
