Abstract
A receiver ( ) for providing chip-to-chip communication in a superconductor integrated circuit. The receiver ( ) includes a detector circuit ( ) for asynchronously receiving an input current, a splitter circuit ( ) connected to the detector circuit ( ) for generating first and second signals, a delay circuit ( ) receiving the second signal from the splitter circuit for generating a delayed signal and a register circuit ( ) receiving the first signal from the splitter circuit ( ) and the delayed signal from the delay circuit ( ) for producing a single flux quantum (SFQ) pulse. The receiver ( ) according to the present invention provides an asynchronous chip-to-chip communication between a multi-chip superconductive circuit having low input current without an external rf clock.
