| Abstract(in English) | Superconductive Single-Flux-Quantum (SFQ) circuits are able to realize ultimate high-speed and low-power consumption devices. Thus, they are expected to be a key device to solve power dissipation problems in future networks. We are developing a real-time oscilloscope system which effectively derives the high-speed nature in the SFQ circuit. A high-speed Analog to Digital Converter (ADC) is the key component of the system. We proposed a new ADC circuit which is predicted to exceed 150GS/s without any interleaves. The new ADC circuit was fabricated and tested with 3 bits accuracy at 10GHz input signal. We are also developing an error correction circuit which prevents uncertainty in threshold of upper bits. This circuit requires high-speed switching corresponding with sampling frequency in the ADC. We already confirmed 30GHz operation of the circuit. Operation speed of these circuits will be improved by increasing critical current density of Josephson junctions used in them. We also succeeded a SFQ circuit operation by 40Gb/s optical input with less than 10^<-12> bit error rate. |
