Abstract
A superconducting circuit is disclosed for fast digital readout of on-chip diagnostics in an array of devices in an integrated circuit. The digital readout comprises a digital RSFQ multiplexer to select the readout channel. This permits a large number of devices to be tested with a minimum of input and output lines. The devices may comprise digital devices (such as elementary RSFQ cells), or analog devices (such as inductors, resistors, or Josephson junctions) with a SQUID quantizer to generate a digital signal. The diagnostic array and the digital multiplexer are preferably configured to operate as part of the same integrated circuit at cryogenic temperatures.
