摘要： An analog-to-digital converter quantizer and bidirectional counter using superconducting quantum interference devices (SQUID's) as the principal elements. A double-junction non-latching SQUID is used as a quantizer to produce unipolar output pulses on two different output lines, indicative of positive and negative increments of change in an analog signal current. The unipolar pulses are then counted in a bidirectional counter that employs double-junction non-latching SQUID's as counter stages and as logic gates for the propagation of carry and borrow signals from stage to stage.

摘要： A superconducting variable phase shifter (10) providing improved performance in the microwave and millimeter wave frequency ranges. The superconducting variable phase shifter includes a transmission (18,20,22) line and an array of superconducting quantum interference devices (SQUID's) (14) connected in parallel with and distributed along the length of the transmission line. A DC control current IDC varies the inductance of the individual SQUID's and thereby the distributed inductance of the transmission line, thus controlling the propagation speed, or phase shift, of signals carried by the transmission line. The superconducting variable phase shifter provides a continuously variable time delay or phase shift over a wide signal bandwidth and over a wide range of frequencies, with an insertion loss of less than 1 dB. The phase shifter requires less than a milliwatt of power and, if one or more of the Josephson junctions (24) fails, the whole device remains operational, since the SQUID's are connected in parallel.

摘要： A device for use as an analog-to-digital converter or a digital magnetometer using a double-junction superconducting quantum interference device (SQUID) and having an extremely fine sensitivity, but a large dynamic range and the ability to handle rapid signal slew rates. The SQUID receives a composite signal, including the analog signal, a correction signal, and a high-frequency dither signal, the latter being selected to produce two output pulses from the SQUID when operated at a quiescent operating point. Departure from the operating point is detected by monitoring the SQUID output pulses and controlling a feedback register to record the degree of movement from the operating point. The feedback register provides the less significant bits of digital output from the converter. The value stored in the feedback register is also converted to analog form and fed back to the SQUID as the correction signal, thereby locking the device onto the desired operating point. Rapid or slow movement equivalent to more than one flux quantum is also detected in the device, and is recorded in an integer register, which provides the more significant bits of the digital output.
