Abstract: From the Publisher: Distortion Analysis of Analog Integrated Circuits provides both qualitative and quantitative insight into the nonlinear behavior of analog integrated circuits at low and high frequencies. General techniques to suppress nonlinear behavior such as pre-distortion, linear and nonlinear feedback are explained in detail and illustrated with realistic examples. In this way the book fills the gap between the theory of nonlinear systems and practical analog integrated circuits. Distortion Analysis of Analog Integrated Circuits is essential reading for practicing analog and mixed-signal design engineers and researchers in the field. It is also suitable as a text for an advanced course on the subject.

...read moreread less

Abstract: Recent efforts to address microprocessor power dissipation through aggressive supply voltage scaling and power management require that designers be increasingly cognizant of power supply variations. These variations, primarily due to fast changes in supply current, can be attributed to architectural gating events that reduce power dissipation. In order to study this problem, the authors propose a fine-grain, parameterizable model for power-delivery networks that allows system designers to study localized, on-chip supply fluctuations in high-performance microprocessors. Using this model, the authors analyze voltage variations in the context of next-generation chip-multiprocessor (CMP) architectures using both real applications and synthetic current traces. They find that the activity of distinct cores in CMPs present several new design challenges when considering power supply noise, and they describe potentially problematic activity sequences that are unique to CMP architectures

Abstract: The aim of this paper is to analyze the power quality of a low-voltage distribution or a stand-alone network with different grid connected power converter topologies. Passive harmonic mitigation techniques are still attractive solutions in power converters. However, these solutions give different harmonic performances at a system level, where a large numbers of converter units are connected in parallel at a point of common coupling. This is due to harmonic cancellation within parallel converter at the system level, which depends on many different factors. Therefore, in this paper, the harmonic performance of a small grid system has been analyzed with respect to different grid and power electronic parameters. This paper also elaborates the importance of phase angle values of current harmonics in order to analyze the power quality of a grid. Harmonic performances of different three-phase power converter topologies have been compared individually. The analysis at the system level has been further extended by including single-phase converters in parallel with the three-phase power converters. A comprehensive modeling and simulation have been carried out in SABER and MATLAB/Simulink to verify the proposed analysis.
