  • Abstract
    We investigated high-Tc superconducting sampler circuits by computer simulation and proved that our latest version of sampler circuit can operate with bandwidth over 100 GHz. In our conventional sampler circuit, we found several problems in its circuit design. An improved sampler circuit, which has additional reset junctions in the dc/SFQ and SFQ/dc parts of the circuit and has a Josephson transmission line with an optimized dc bias in front of the comparator, accurately reconstructed signal waveforms with bandwidth above 160 GHz for a typical IcRn product of 1 mV in the simulation.
