Patent abstract

A programmable phase shifter is constructed of Rapid Single Flux Quantum (RSFQ) logic elements. The logic elements may include an RSFQ inverter and an RSFQ T flip-flop. A digital word comprising N bits is used to control the amount of phase shift and the phase shifter selectively imparts a respective phase shift for any of 2N states that can be represented by the digital word. The RSFQ logic elements utilize Josephson junctions which operate in the superconducting temperature domain.
