Phase noise in distributed oscillators [PDF]
Electronics Letters, 2002 The phase noise of a distributed oscillator is evaluated very simply by identifying an effective capacitance equal to the total capacitance distributed along the transmission lines. The contributions of the various passive and active noise sources to the total phase noise are calculated revealing several guidelines for improved distributed oscillator ...

Noise-induced synchronization for phase turbulence [PDF]
Physics Letters A, 2003 Phase turbulence is suppressed by applying common noise additively to the Kuramoto-Sivashinsky type equation, and the noise-induced phase synchronization is realized. The noise strength necessary for the suppression of phase turbulence is evaluated theoretically.

PHASE AND FREQUENCY NOISE METROLOGY [PDF]
Frequency Standards and Metrology, 2009 As a consequence of a general trend in the physics of oscillators and clocks towards optics, phase and frequency metrology is rapidly moving to optics too. Yet, optics is not replacing the traditional radio-frequency (RF) and microwave domains. Instead, it adds tough challenges.

Discrete Dynamics in Nature and Society, 2022 Noise exists widely in the nervous system, and plays a crucial role in the nervous system information processing. Noise can not only enhance but also weaken the ability of the nervous system to process information.

Phase noise and amplitude noise in DDS [PDF]
2012 IEEE International Frequency Control Symposium Proceedings, 2012 Their article reports on the measurement of phase noise and amplitude noise of direct digital synthesizers (DDS), ultimately intended for precision time and frequency applications. The DDS noise S ϕ (f) tends to scale down as 1/ν 0 2, until the noise hits the limit due to the output stage.

Phase-Noise and Amplitude-Noise Measurement of DACs and DDSs [PDF]
2019 Joint Conference of the IEEE International Frequency Control Symposium and European Frequency and Time Forum (EFTF/IFC), 2019 This article proposes a method for the measurement of Phase Noise (PN, or PM noise) and Amplitude Noise (AN, or AM noise) of Digital-to-Analog Converters (DAC) and Direct Digital Synthesizers (DDS) based on modulation-index amplification. The carrier is first reduced by a controlled amount (30-40 dB) by adding a reference signal of nearly equal ...

Single-Stage Injection-Locked Frequency Sixtupler in CMOS Process
IEEE Access, 2022 High multiplication-factor even-modulus frequency multipliers are often configured as multi series frequency multipliers. This paper designs a single-stage $LC$ -tank injection locked frequency sixtupler (ILFS) fabricated in $0.18~\mu \text{m}$ CMOS ...

Influence of local oscillator phase noise on noise figure of wideband receiver
Dianzi Jishu Yingyong, 2020 Based on the analysis of the influence of wide-band local oscillator with different phase noise on the received noise figure of the wideband receiver, a wideband mixer is used to actually test to obtain the phase noise of the mixer IF signal, through the
