Drain and gate bias dependent fluctuations of flicker noise of MOSFETs are explained in terms of carrier concentration distributions in a MOSFET channel. A proposed model well describes the increase of the fluctuation in the saturation region of operation. In addition, the gate bias dependence of the fluctuation in the saturation region can also be calculated using the model. Our model predicts...

Studies show that all the published work in flicker correction to date only deals with black and white motion pictures. In this paper, we will look into the problem of flicker correction in color motion pictures and propose a method to address this problem. The method is based on a simplified flicker parameter model developed by us in [5] which was originally used for flicker correction in blac...

The problem of information extraction from discrete stochastic time series, produced with some finite sampling frequency, using flicker-noise spectroscopy, a general framework for information extraction based on the analysis of the correlation links between signal irregularities and formulated for continuous signals, is discussed. It is shown that the mathematical notions of Dirac δ and Heavisi...

This study reports the flicker noise characteristics in GaAs-based MOSFETs for the first time. With the improvement in Ga 2 O 3 (Gd 2 O 3) insulators, GaAs MOSFETs reveal the possibility for high-speed and high-power applications, resulting from an electronic mobility that is about five times greater than that in Si, and the advantage of semi-insulating substrate. The DC and RF characteristics ...

2014 An effective-medium theory, for the flicker (1/f) noise amplitude, is formulated for random resistor networks. Close to the percolation threshold pc, the magnitude of the noise is shown to diverge as (p pc)-03BA, with 03BA = 1 for both site and bond percolation models. The exponent 03BA is also calculated in the framework of two different renormalization group transformations. The possible...

The flicker noise spectroscopy which is a new phenomenological method for the retrieval of information contained in chaotic time signals, is based on the analysis of recognizable irregularities (pulse, jumps, and discontinuities of derivatives of various order). This method is applied to the ULF (ultra-low-frequency) data observed at Guam in 1992– 1994, in order to study the temporal nonlinear ...

measurement of magnitude and frequency of the voltage flicker is very important for monitoring andcontrolling voltage flicker efficiently to improve the network power quality. this paper presents twonew methods for measurement of flicker signal parameters using shuffled frog leaping algorithm(sfla) and imperialist competitive algorithm (ica). this paper estimates fundamental voltage andflicker ...
