Claim 15:
16. Reciprocal quantum logic (RQL) superconducting bias-level sensing circuitry for sensing bias levels provided to operational RQL circuitry of an RQL integrated circuit (IC), the bias-level sensing circuitry comprising a plurality of bias-level sensors each comprising a pulse generator driven by an AC bias signal derived from one or more AC clock resonators, the pulse generator having at least one of:
an AC clock resonator bias tap that couples to at least one of the one or more AC clock resonators of the RQL IC that is weaker or stronger than an AC clock resonator bias tap of a Josephson transmission line (JTL) in the operational RQL circuitry of the RQL IC, or
a Josephson junction (JJ) having a larger or smaller critical current than a JJ in the operational RQL circuitry of the RQL IC.
