Measurement and modeling of noise parameters for desensitized low noise amplifiers

Proceedings of the IEEE 2004 Custom Integrated Circuits Conference (IEEE Cat. No.04CH37571), 2004
It can be shown that devices with low noise resistance (R/sub n/) values can significantly relax the noise-input match trade-off in LNA design, resulting in desensitized wideband LNAs. In this paper, we show that the measurements of such devices are error-prone and can cause modeling and simulation inaccuracies.

Novel Noise Parameter Determination for On-Wafer Microwave Noise Measurements

IEEE Transactions on Instrumentation and Measurement, 2008
A novel method to determine the noise parameters of receivers or devices under test (DUTs) for on-wafer microwave noise measurements is presented. An iterative technique is utilized, and fast convergence is achieved by the proposed impedance selection principle. This proposed method reduces the parameter variations in the conventional methods.

Simplified noise model parameter estimation for signal-dependent noise

Signal Processing, 2014
In this paper, we present a noise parameter estimation method using a simplified signal-dependent noise model. The generic Poisson-Gaussian noise model is simplified to a Gaussian-Gaussian noise model. From the simplified noise model, we experimentally verify that the value obtained by the robust median estimator is almost the same as the mean of the ...

Bandwidth Conversion of ELF Noise Parameters

IEEE Transactions on Communications, 1984
The Field-Lewinstein-Modestino model represents ELF noise as the sum of Gaussian and impulsive components. This model has proven to be accurate and is especially convenient for analysis and simulation. However, the parameters of the model are bandwidth dependent and have been measured for only a few specific bandwidths.

Analytical Modeling of MOSFETs Channel Noise and Noise Parameters

IEEE Transactions on Electron Devices, 2004
Simple analytical expressions for MOSFETs noise parameters are developed and experimentally verified. The expressions are based on analytical modeling of MOSFETs channel noise, are explicit functions of MOSFETs geometry and biasing conditions, and hence are useful for circuit design purposes.

Estimation of signal parameters in the presence of noise

Transactions of the IRE Professional Group on Information Theory, 1954
This paper is concerned with certain applications of the estimation theory of Fisher and Cramer[1] to the problem of estimating signal parameters in the presence of noise. Specifically, the situation to be treated is as follows.

Signal Parameter Optimization for the Impulsive Noise Channel

IEEE Transactions on Communications, 1980
Summary: A common assumption in the analysis of impulsive noise channels is that at most one noise impulse occurs to affect any given decision. In practice, this assumption is not always valid. However, in this work it is shown that optimum signals parameter values can be determined subject to the single noise impulse assumption.

On the determination of noise parameters of low‐noise transistor devices

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2015
AbstractIn this paper, we discuss the experimental determination of noise parameters for high‐electron‐mobility transistor (HEMT) devices and analyze the problems encountered with conventional extraction techniques. HEMT devices are distinguished by a very small minimum noise figure of only a fraction of a dB, and this minimum noise is accomplished ...

Noise Parameter Estimation from Quantized Data

Proceedings of the 2006 IEEE International Workshop on Advanced Methods for Uncertainty Estimation in Measurement (AMUEM 2006), 2006
In this paper, the parametric estimation of the variance of white Gaussian noise is considered when available data are obtained from a quantized noisy stimulus. The Crameacuter-Rao lower bound is derived, and the statistical efficiency of a maximum-likelihood parametric estimator is discussed, along with the estimation algorithm proposed in IEEE ...

Parameter estimation of a decaying exponential in noise

2009 16th International Conference on Digital Signal Processing, 2009
The estimation of the parameters of a decaying complex exponential in noise was examined by Bertocco et al. who developed a frequency domain interpolator using two DFT coefficients around the maximum bin. Quinn, on the other hand, and more recently Aboutanios and Mulgrew (A&M), proposed similar frequency estimators for the undamped case. In this paper,
