PURPOSE:To eliminate the need for a sweeping device and to obtain a circuit operating stably with high precision, by connecting plural circuits having different switch time in parallel, making the output common and activating an arbitrary one of the plural circuits. CONSTITUTION:In Figure, 1-10 are Josephson elements. Series circuits comprising inductances 11-20 and resistors 21-30 respectively are connected as the load of the elements. The switch time of each element depends on the ratio of the inductance to the resistor, and 10 sets of the Josephson elements have different time constants by each 5-pico-second. An external pulse generated at a prescribed period is selected at a switch 31 and applied to the Josephson elements, then 10 kinds of different pulse leading times corresponding to the 10 sets of the elements are obtained. The output is made common at a terminal 34, this is inputted to a pulse generating circuit 35, the operated timing interval depends on the operating point of a pulse generator 35 and the current supply path to a delay circuit. Further, the components other than the switch 31 are placed in an environment of an ultra-low temperature. |
