Statistical properties of a filtered Poisson process with additive random noise: Distributions, correlations and moment estimation [PDF]
, 2017 Filtered Poisson processes are often used as reference models for intermittent fluc- tuations in physical systems. Such a process is here extended by adding a noise term, either as a purely additive term to the process or as a dynamical term in a ...

Millimeter-wave noise modeling of nanoscale MOSFETs
Dianzi Jishu Yingyong, 2018 Based on the physical structure of 40 nm MOSFETs, this paper establishes a unified MOSFET millimeter-wave noise model to characterize the characteristics of drain-current noise, inducted gate-current noise and cross-correlation noise between them.

Transport of quantum noise through random media [PDF]
, 2004 We present an experimental study of the propagation of quantum noise in a multiple scattering random medium. Both static and dynamic scattering measurements are performed: the total transmission of noise is related to the mean free path for scattering ...

Influence of Noise on Scattering-Parameter Measurements
IEEE Transactions on Microwave Theory and Techniques, 2020 We present a general model of noisy scattering-parameter (S-parameter) measurements performed by a vector network analyzer (VNA). The residual error of the S-parameter due to the noise is examined to appear like a complex Gaussian quotient. The statistical analysis of the residual error is given, and relevant statistical quantities are derived and ...

An Improved Method for InP HEMT Noise-Parameter Determination Based on 50-Ω Noise Measurements
IEEE Journal of the Electron Devices SocietyIn this paper, we propose an improved method for extracting the four noise parameters of InP HEMT devices based on a 50- $\Omega $ noise measurement system. The noise equivalent circuit and noise correlation matrix technique is combined with 50- $\Omega
