Abstract Adiabatic quantum-flux-parametron (AQFP) circuits are a promising technology as ultra-low-power logic because their energy consumption is reduced considerably by operating them adiabatically. The AQFP circuits are driven by an AC current source that periodically applies and removes their bias current. However, if external sources are used for supplying the AC bias at high-frequency, on-chip passive network will be larger and the AC bias dissipation at the interconnection becomes higher. In this study, we propose on-chip AC power sources operated by DC power sources. The proposed AC power source is composed of a superconducting resonator and a DC-powered Josephson relaxation oscillator which is coupled to the resonator. It converts DC current into AC current and supplies the AC current magnetically to AQFP circuits coupled to the resonator. We designed and implemented the AC power source, whose target frequency is 4.8 GHz, by using the ISTEC Nb standard process. Simulation results show that its power consumption is a few $mu$W and its correct operation was experimentally demonstrated, where the AC output current amplitude can be varied from 1 mA to 8 mA by its DC input current. These results indicate that AQFP circuits can be driven by external DC power sources using the on-chip AC power sources. |
