    摘要: A superconducting A/D converter (10) has an error correction system (70) for eliminating non-linearities in a primary quantizer (30). The converter (10) includes a primary quantizer (30), a primary SFQ counter (50), and the error correction system (70). The primary quantizer (30) generates primary SFQ pulses based on an average voltage of an analog input signal. The primary SFQ counter (50) converts the primary SFQ pulses into a digital output signal based on a frequency of the primary SFQ pulses. The error correction system (70) corrects the digital output signal based on the analog input signal and the primary SFQ pulses. Using the primary SFQ pulses to correct the digital output signal allows the converter (10) to take into account the non-linearities of the primary quantizer (30).

    摘要: A superconductor circuit (50) for providing active timing arbitration between SFQ pulses. The superconductor circuit (50) includes a first superconducting transmission line (52) having at least one inductor (54) for transmitting first input pulses, and a second superconducting transmission line (62) having at least one inductor (64) for transmitting second input pulses that are correlated to the first input pulses. The first and second superconducting transmission lines (52, 62) are coupled together in order to generate a flux attraction between the first and second input pulses for reducing relative timing uncertainty.
