Rapid single flux quantum pulse multiplier

Abstract:

A method of generating an output signal based on a single flux quantum (SFQ) pulse includes receiving the SFQ pulse and splitting it into a first path and a second path. The split SFQ pulse of the second path is stored in a latch. A second splitting of the split SFQ pulse of the first path is provided to provide a first output signal and a second output signal of the first path. The second output signal is delayed by a delay Josephson transmission line (JTL). An output of the delay JTL is provided as a clock input to the latch. The first output of the first path is recombined with an output of the latch to provide an output signal.
