摘要： A two-dimensional SQIF array and methods for manufacture can include at least two bi-SQUIDs that share an inductance. The bi-SQUIDs can be combined to establish a diamond-shaped cell. A plurality of the diamond shaped cells can be packed tightly together so that each cell shares at least three cell junctions with adjacent cells to establish the SQIF array. Because of the close proximity of the cells, the effect that the mutual inductances each cell has on adjacent cells can be accounted for, as well as the SQIF array boundary conditions along the array edges. To do this, a matrix of differential equations can be solved to provide for the recommended inductance of each bi-SQUID in the SQIF array. Each bi-SQUID can be manufactured with the recommended inductance to result in a SQIF having an increased strength of anti-peak response, but without sacrificing the linearity of the response.

摘要： A system for linearizing the output of a high power amplifier (HPA) designed to transmit an RF modulated signal includes in its transmit section a digital up-converter for processing baseband input signals and generating a desired digital RF waveform, T(s). The desired digital RF waveform T(s) is then fed to a digital predistorter circuit for producing a predistorted digital RF waveform P(s)T(s) which, as modified, may be applied via a high sampling speed high linearity digital to analog converter to the high power amplifier (HPA) to produce an output signal which is a linear function of the baseband input signal. The digital predistorter circuit may be of the adaptive type or of the predictive type. Circuits embodying the invention may include encoding circuitry for converting multi-bit signals to a serial stream of single-bit pulses for enabling simplification in the digital to analog conversion. In accordance with the invention, corrections for non-linearity of the HPA may be made directly on the RF waveform using ultra-high speed superconducting electronics (SCE) and decreasing the time delay between sensing a transmitted signal and generating a correcting (linearizing) signal.

摘要： A superconducting quantum interference devices (SQUID) comprises a superconducting inductive loop with at least two Josephson junction, whereby a magnetic flux coupled into the inductive loop produces a modulated response up through radio frequencies.

摘要： The invention includes a novel differentiator cell, a novel resample unit cell, and precision synchronization circuitry to ensure proper timing of the circuits and systems at the anticipated ultra-high speed of operation. The novel differentiator cell includes circuitry for combining a carry input signal, a data bit signal and the output signal of a NOT cell and applying the signals as distinct and separate pulses to the input of a toggle flip-flop (TFF) for producing an asynchronous carry output and a clocked data output. The novel differentiator cells can be interconnected to form a multi-bit differentiator circuit using appropriate delay and synchronization circuitry to compensate for delays in producing the carry output of each cell which is applied to a succeeding cell. The novel resample cell includes a non-destructive reset-set flip-flop (RSN) designed to receive a data bit, at its set input, at a slow clock rate, which data is repeatedly read out of the RSN at a fast clock rate, until the RSN is reset. The novel differentiator and resampler cells can be interconnected, for example, to form the differentiator and up-sampling sections of a digital interpolation filter (DIF). Also, the relative clocking of bit slices (columns) in such a DIF may be achieved by using the fast clock signal to synchronize the slow clock which controls data entry. The circuits of the invention can be advantageously implemented with Josephson Junctions in rapid-single-flux-quantum (RSFQ) logic.
