ABSTRACT:
A Josephson junction amplifier comprising an array of series connected Josephson junctions which are maintained in a finite voltage, mutually electromagnetically phase-locked state. An input signal is applied across a first group of one or more but less than all of the Josephson junctions, and the output is taken across a second group of the junctions which has a greater number of junctions than the first group. Alternatively, two arrays may be connected in parallel to provide stable electromagnetic phase locking.
