Abstract

PURPOSE:To detect a signal low in noise and having a wide band, by detecting the signal of a quantum flux parametron by a semiconducting quantum interference device. CONSTITUTION:A DC bias current is applied to a DC semiconducting quantum interference device DC-SQUID so as to bring the DC-SQUID to a voltage state only by said bias current and, unlike the superconductive-voltage state transition in a conventional method, a signal is detected on the basis of the change in a voltage value of a limited one by the current signal from a quantum flux parametron QFP. The QFP is composed of a superconductive loop 5 constituted by connecting a circuit pair composed of a Josephson element 7 and an exciting inductor 3 as well as a Josephson element 2 and an exciting inductor 4. The DC-SQUID 10 forms a superconductive loop along with Josephson elements 11, 12, inductors 15, 16 and the inductors 13, 14 magnetically connected to a load inductor 8'. Since the drive frequency of an RF-SQUID is higher than that of an input signal and a sine wave, noise can be simply removed.
