Variable frequency division using cryoelectric single-flux quantum circuits

It is the object of the invention to propose an electronic circuit allowing the division of high frequencies at an adjustable or regulable ratio with a low power loss using a single-flux quantum logic circuit with Josephson contacts.

According to the invention, the object is achieved by using an array of a plurality of Josephson contacts with the output voltage being picked up after a determined number of Josephson contacts within the array, instead of using a pair of two series-connected Josephson contacts contained in a standard circuit for converting flux quantum to voltage representation of information. The present invention relates to a circuit arrangement which contains single-flux quantum circuits with Josephson contacts and is used for the processing of incoming digital signals, e.g., for frequency division, as a counter element, or as a decimation filter with the resulting signal being provided at the circuit output, and single-flux quantums being used for the representation of information.
