Approximate formulas that yield the resonance amplitude of symmetric two‐junction interferometers have been derived using step‐by‐step linearizations and approximations based on physical arguments. The resonance amplitude is found to strongly d

Measurements on large arrays of Josephson interferometers were carried out to obtain individual device parameters and their spread. Each array contained 784 identical interferometers with junction diameters of 5 and 7 μm and was deposited on a 6.35

Resonance dc structures are experimentally investigated in two‐junction interferometers in which the device Q is adjusted to low values with an external resistor connected across the main device inductance. The measurements agree well with the resu

Solutions of the equation of motion of Josephson junction devices are approximated by analytical relations in the pronounced nonlinear range of small voltages. The minimum current at which the junction switches back into the net zero voltage state is

Transitions from the zero‐voltage to the voltage state have been directly measured on large (≃104 μm2) Josephson junctions. By adjusting the current load, the switching times (10–90%) were varied from 60 to 400 psec. Good agreement was found b

Operation of a DRO single flux quantum Josephson junction memory cell is described. Writing and sensing is performed with coincident currents. The device acts as its own sense detector, switching to the gap voltage if a flux quantum was stored. Dense

Josephson interferometers are shown to operate as oscilators (≳1 μW power) and as narrow‐band receivers. Their operation is described in the context of a potential intracomputer communications network with an ultimate channel capacity of the ord
