Abstract:
Supercooled electronics often use Rapid Single Flux Quantum (RSFQ) digital circuits. The output voltages from RSFQ devices are too low to be directly interfaced with semiconductor electronics, even if the semiconductor electronics are cooled. Techniques for directly interfacing RSFQ digital circuits with semiconductor electronics are disclosed using a novel inverting transimpedance digital amplifier in conjunction with a non-inverting transimpedance digital amplifier to create a differential transimpedance digital amplifier that permits direct interfacing between RSFQ and semiconductor electronics.
