Superconducting dual function digitizer

摘要

A dual function superconducting digitizer circuit which can selectively function either as an analog-to-digital converter (ADC) or as a time-to-digital converter (TDC). Superconducting ADCs and TDCs can provide performance far superior to that obtained using conventional electronics by taking advantage of the intrinsic properties-high switching speed, quantum accuracy, dispersion-less transmission lines, radiation hardness, and extremely low power dissipation-of superconductivity. Since both ADC and TDC functions are desired in most measurement systems, a dual-function digitizer is not only more attractive from a system integration perspective but is also more marketable.
