| Abstract(in English) | On-chip double relaxation oscillation SQUID (DROS) with a digital flux locked loop (FLL) circuit was demonstrated for high sensitive magnetic flux sensor and SQUID amplifier. A digital FLL circuit is composed of a 6-bit Up/Down counter and a 6-bit R-2R ladder-type D/A converter. Each circuit has designed using 4JL-gates which are driven by a two-phase power supply. Dynamic simulation was done for whole circuit at a frequency of 670 MHz. The DROS layout was carried out using 6 kinds of logic cells based on a standard cell method. The digital DROS was fabricated using a Nb/AlO_x/Nb junction technology with a minimum line width of 3 μm. The on-chip DROS circuit occupied an area of 1.9 mm × 3 mm. |
