Description
The superior performance of arrays of superconducting detectors for
high energy physics is well known, in terms of their sensitivity and
speed. These signals are generally amplified and read out and
analyzed using room-temperature digital electronics some distance
away. However, an alternative approach is to carry out data
conversion and partial analysis using digital superconducting
electronics located close to the cryogenic detectors. This can be
achieved using ultrafast, ultra-low-power superconducting logic based
on single-flux-quantum (SFQ) pulses. Relevant devices include
analog-to-digital converters (ADCs), time-to-digital converters
(TDCs). digital filters, and digital control logic. Performance of
these digital circuits is discussed together with applications to
superconducting detector arrays and superconducting qubits.
