    A self-consistent approach for analyzing phase velocities and resonances in modern Josephson junction geometries is presented. The analysis is based on the two-dimensional wave equation for the scalar current potential. The boundary conditions for the normal and tangential derivatives of the scalar potential are given. These follow from conservation of the normal components of sheet current and ma... View full abstract»

    The formulation of Josephson circuit equations in the DC state is discussed and a mixed-mode approach that combines the nonlinear solution method of source-stepping and time-domain method of numerical integration is proposed. Since Josephson circuit equations are often multivalued, the mixed-mode algorithm follows the paths of the independent sources, detects ill-conditioned points, and converges ... View full abstract»

    The fabrication and testing of single comparators at low and high speeds (up to 10-GHz input bandwidth) to determine basic functionality, dynamic range, linearity, noise level, and dynamic distortions are described. A 4-b converter was tested at low speed without errors. The results indicate that a 6-b converter may be constructed of these comparators with very good linearity and 8 b should be ach...

    A nonlinear transmission line can generate a shock wave. However, dispersion and granularity of the line offset the theoretical discontinuity associated with the shock wave and force the wave to a stable form. Such stable waveforms are examined in the context of superconducting technology. In particular, the characteristics of a tranmission line composed of a series of Josephson junctions are stud...
