DEVICE FOR REDUCING PHASE NOISE

摘要

Disclosed is a device for reducing the phase noise of a signal (Sin) emitted by a quasi-periodic source having a basic frequency f0. Said device is provided with a superconducting circuit comprising an active line for transmitting voltage pulses by transferring flux quanta F0. Said circuit is defined so as to be provided with a characteristic frequency fc such that 0.3 fc is smaller than or equal to the basic frequency f0 of the quasi-periodic signal (Sin) applied at the input while supplying a voltage pulse signal having the basic frequency f0 at the output.
