High resolution superconductive sampling circuit.

摘要

The invention is an all-soliton sampler for accessing very high speed circuits. A solution is switched in two parallel branches, one including the device under test (7) and the other including a programmable delay line (8) implemented in soliton devices. The outputs of these two branches are used as controls to a soliton comparator (9 to 14) which, in turn, controls a Josephson detector gate (17). This circuit permits a relatively slow rise time external trigger pulse to initiate an extremely narrow sampling pulse.
