Abstract: A design of an up/down counter composed of 4-Junction Logic (JL) gates and the digital/analog (D/A) converter using an R-2R ladder circuit is presented to realize the digital flux locked-loop (FLL) circuit. The 4 JL gates with the Superconducting QUantum Interference Device (SQUID) regulator is developed and the correct logic operations are successfully confirmed using fabricated 4JL gates.
