This paper reports on a superconductive analog-to-digital converter which uses a dc SQUID as a quantizer and a flip-flop counter as a digitizer that has been designed, fabricated, and tested. The circuit was fabricated using a ten-level niobium process. Tests at 4.2 K demonstrated counting to the full twelve-bit accuracy of the design, monotonic A/D conversion with linearity to less than 1 LSB over the more than nine-bit range of conversion, read-on-the-fly operation with counter overflow, and counter operation with a gate current bus.
