1. A diagnostic circuit comprising:
a superconducting quantum interference device (SQUID) configured to be coupled to a test circuit such that an electronic noise present in the test circuit induces a first current that flows through the SQUID; and
a current path configured to receive a second current that flows through the SQUID, wherein the SQUID is configured to generate an output in a form of:
a first voltage in response to a sum of the first current and the second current being less than a threshold current, and
a second voltage in response to the sum of the first current and the second current being greater than the threshold current.
