Title:
SUPERCONDUCTING INTEGRATED CIRCUIT
Document Type and Number:
Japanese Patent JPH01313978
Kind Code:
A
Abstract:
PURPOSE:To eliminate the malfunction of a circuit by providing a DC power supply driving circuit part independently of an AC power supply driving circuit part, separating the grounging surface by both of the parts, and detecting the real signal output component of the latter by the former. CONSTITUTION:The signal output of an AC power supply driving circuit 105 is detected by a DC power supply driving circuit 106. The AC power supply driving circuit 105 and the DC power supply driving circuit 106 are subjected to insulative isolation by grounding surfaces 102, 103. A signal transmitted from the AC power supply driving circuit 105 to the DC power supply circuit 106 is only a real signal component, and the DC power supply driving circuit 106 detects its generating magnetic flux. As a result, even if the grounded potential of the AC power supply driving circuit 105 side is fluctuated by AC power supply current of high frequency and large amplitude, the output signal of the DC power supply driving circuit 106 does not fluctuate, thereby eliminating the malfunction of a circuit.
