Noise in Semiconductor Devices

Provides an overview of the physical basis of noise in semiconductor devices, and a detailed treatment of numerical noise simulation in small-signal conditions. It presents innovative developments in the noise simulation of semiconductor devices operating in large-signal quasi-periodic conditions. The book presents a comprehensive treatment of the numerical simulation of semiconductor devices. After an overview of the basic physics of fluctuations in semiconductors, noise modelling techniques are introduced for the small-signal case. In particular, a detailed treatment is devoted to Green's function approaches such as the Impedance Field Method. Then, the numerical implementation of such approaches within the framework of multi-dimensional numerical device models is discussed in detail with reference to the customary Finite-Boxes discretization scheme. Finally, the topic of large-signal noise simulation is addressed within the framework of the Harmonic Balance approach, and implementation details are given for the non-autonomous case. The application fields covered range from low-noise, small-signal amplifiers to nonlinear circuits such as RF and microwave frequency multipliers and mixers.
