概要
- 論文の詳細を見る
We have been developing single flux quantum (SFQ) sampler using high-T_c superconductor. It is a device for measuring electrical signal waveforms by using sharp current pulses accompanying SFQ. A computer simulation reveals that the bandwidth over 100 GHz is possible for one of our latest versions of the sampler circuits. To realize circuit parameters required in the simulation, a high-T_c superconducting (HTS) circuit fabrication process using a lower ground plane structure has been developed. Up to now, we have succeeded in observing sinusoidal current waveforms with frequencies up to 45 GHz in a sampler circuit with a superconducting pickup coil which magnetically detects current signals without electrical contacts.
