A nonuniform, one-dimensional tunnel junction array was proposed to promote phase-locking to an ac pump signal. The tunnel resistances of the junctions in one part of the array provided phase restoration for electrons tunneling in the array. The tunnel resistances in the other part of the array were designed to provide a time delay with minimal jitter. The results show that phase-locking of the tunneling is possible at the fundamental and at the one-half subharmonic of the pump frequency.
