Chapter 1 SUBSTRATE NOISE : ANALYSIS , MODELS , AND OPTIMIZATION
نویسندگان
چکیده
In this paper we address the main problems posed by substrate noise from two complementary points of view. We look at the effects of substrate noise on performance and reliability in digital, analog and mixedsignal circuits. The mechanisms underlying noise generation, injection, and transport are also analyzed. Solutions to the substrate noise problem using design and layout techniques, as well as accurate analysis and optimization are discussed.

Mechanisms of auditory perceptual learning
Practice improves performance on many basic auditory tasks. However, while the phenomenon of auditory perceptual learning is well established, little is known about the mechanisms underlying such improvements. What is learned during auditory perceptual learning? Here I attempt to address this question by applying models of performance to behavioural response data, and examining which parameters...
متن کاملComparison of Methods for Developing and Using Dynamic Reduced Models for Design Optimization
This thesis compares different methods used in developing and using dynamic reduced models for design optimization. Several methods have been used for forming functional approximation models with which the GA search is performed more efficiently. The informed operators approach for search speedup is discussed. Another hypothesis-instantiation approach in using reduced models has been tested and...

In this thesis, signal processing strategies for the reduction of undesired interfering signals in binaurally recorded signals are derived und described. The properties of the different processing strategies are discussed and the processing performance is investigated using artificial signals. Two hearing aid algorithms are described that combine different noise reduction strategies and provide...
متن کاملModeling and Analysis of Substrate Coupling in Integrated Circuits by
Substrate coupling in integrated circuits is the process whereby parasitic current flow in the substrate electrically couples devices in different parts of the circuit. Higher levels of integration and higher frequencies of operation make the coupling more pronounced in modern circuit realizations. High levels of integration are desirable in several applications for reducing the overall power d...
متن کاملAnalysis and Optimization of Telephone Speech Command Recognition System Performance in Noisy Environment
This paper deals with the analysis and optimization of a speech command recognition system (SCRS) trained on Czech telephone database Speechdat(E) for use in a selected noisy environment. The SCRS is based on hidden Markov models of context dependent phones (triphones) and mel-frequency cepstral coefficients analysis of speech (MFCC). The main aim is to analyze and to search for the optimal set...
