In this paper, we describe our SFQ circuit design and measurement carried out in SRL-ISTEC. We are studying an oversampling sigma-delta modulator and a counter-type decimation filter with multistage structure for developing AD converters for software-defined radio application. We are also developing a superconducting memory, whose peripheral circuits are constructed with SFQ circuits.
