Operation of a superconducting analog-to-digital converter at short conversion times
Richard L. Kautz, Frances L. Lloyd
Abstract
The accuracy of a six-bit superconducting analog-to-digital converter has been tested at short conversion times. The accuracy was found to be good for conversion times down to 0.5 ns but significant errors were observed at a conversion time of 0.1 ns. These errors can be understood in terms of unwanted switching events that occur when the mode boundary separating two flux states is crossed rapidly.
