✦ Synopsis

The in~uence of additive noise on phase transitions in nonlinear chains induced by multiplicative noise is studied[ These chains can be considered as _nite di}erence approximations of nonlinear partial di}erential equations of di}usion type[ The phase transitions considered manifest themselves in the dis! ruption of the symmetry and the birth of new equilibrium states[ In the so!called mean _eld approximation\ it is shown that additive noise signi_cantly shifts the boundaries of the phase transition[

We examine the mechanisms of cross-correlation of white multiplicative noise and white additive noise in a single-mode laser and establish a white-gain-noise model containing such a cross-correlation. We show that the cross-correlation between the white multiplicative noise and the white additive no

## Abstract Channel noise enhancement due to MOSFET scaling and its influence on phase noise estimation of fully integrated VCO have been studied. The channel noise of MOSFET increases due to the hot electron effect of small geometry MOSFET is obvious. The channel noise coefficient, __Ξ³__, of NMOS
