Phase- and Amplitude Noise Suppression using a Josephson Arbitrary Waveform Synthesizer

This paper describes the verification of the phase- and amplitude noise suppression property of a Josephson Arbitrary Waveform Synthesizer (JAWS) circuit. Simulations are performed to gain insight in the improvement in signal-to-noise ratio (SNR) delivered by the JAWS circuit when random amplitude andjitter noise are introduced. Measurements show an improvement for both integrated phase- and amplitude noise of 15 to 40 dB for synthesized frequencies in the range of 0.5-2MHz.
