ABSTRACT:
Disclosed herein are circuits and methods for receiving SFQ data pulses from a superconductor signal source, and first and second clock pulses that are substantially equal in frequency but opposite in phase from clock signal sources, and for encoding and converting the SFQ data pulses into a phase-shift-keying coded dc output voltage. The circuit includes RSFQ T-RS flip-flop means, including quantizing means for storing a current in one of two stable states, which is responsive to the first and second clock pulses and the data pulse, for PSK coding the SFQ data pulses. The circuit also includes a SFQ/DC converter, which is coupled to the quantizing means of the RSFQ T-RS flip-flop means and is responsive to a state of the current stored in the quantizing inductance loop, for converting the PSK coded SFQ data pulses into a PSK coded dc voltage.
