Abstract
A method for improving performance of a superconducting, flux-quantizing analog to digital converter (SFADC), comprising the following steps. The first step involves providing a known digitally-modulated signal as an input to the SFADC. Another step provides for generating an output with the SFADC based on the known digitally-modulated signal. Another step provides for comparing the characteristics of the output with ideal characteristics to identify an individual rapid single flux quantum (RSFQ) element of the SFADC that is contributing one or more of noise and error to the output. Another step provides for altering one or more of a bias, a delay, and a temperature of the individual RSFQ element to reduce one or more of the noise and the error.
