Its static power is zero because of ac flux bias, and its dynamic power is considerably reduced, thanks to the adiabatic switching of the junctions. The lack of high-density memories in the AQFP logic, however, makes it challenging to realize large-scale information processing systems with the use of pure AQFP circuits. We have been developing a Josephson-CMOS hybrid memory to overcome the memory bottleneck in AQFP digital systems. By utilizing the high sensitivity of the AQFP gate, the output current from CMOS memories can be significantly decreased resulting in the reduction of the power consumption. In this article, we designed and fabricated a low-power area-efficient AQFP-CMOS hybrid field-programmable gate array (FPGA), where a CMOS memory is utilized as a rewritable read-only memory to control the AQFP circuits. The AQFP circuit for the AQFP-CMOS hybrid FPGA is composed of logic blocks, switch blocks, and connection blocks, which are clocked by four-phase excitation currents. The AQFP-CMOS hybrid FPGA is fabricated by using the AIST 10 kA/cm 2 Nb high-speed standard process and the Rohm 0.18 μm CMOS process. The area and power consumption of the two-by-two AQFP logic-cell system are estimated to be approximately 6.56 mm 2 and 12.4 nW at 5 GHz operations, respectively. The power consumption of the CMOS memory was estimated to be 1.02 μW assuming the CMOS source voltage of 3 mV. We demonstrated the operation of the AQFP-CMOS hybrid FPGA at low speed by combining the AQFP logic and the CMOS memory.","subitem_description_type":"Abstract"}]},"item_2_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"© 2019 IEEE.
