Hardcover. Condizione: new. Hardcover. This book discusses in detail low-voltage low-power designs for minimizing the hardware resources required by neural network implementations. The novel method presented in this book for an accurate realization of activation functions for artificial neural networks (ANNs), is based on specific superior-order approximation functions. The author describes analog implementations in CMOS technology to increase the speed of operation, while reducing the hardware resources required for obtaining these approximation functions. Original architectures presented in this book, used for implementing previous CMOS computational structures, allow for operation independent of technological errors and temperature variations. SPICE simulations confirm the theoretically estimated results for previously presented CMOS computational structures, developed for ANNs and artificial intelligence applications.

Hardback. Condizione: New. 2009 ed. Voltage references represent important VLSI structures, having multiple appli- tions in analog and mixed-signal circuits: measurement equipment, voltage re- lators, temperature sensors, data acquisition systems, memories, or AD and DA converters. Operating as a subcircuit in a complex system, an important requi- ment for this class of circuits is represented by the possibility of implementation in the existing technology, using the available active and passive devices. The most important performances of a voltage reference circuit are represented by temperature behavior, power supply rejection ratio, transient response and, for the latest designs, by low-power low-voltage operation. Depending on the load - quirements, the output of the circuit can be regulated or unregulated. In order to reduce the sensitivity of the reference voltage with respect to the supply voltage variations, modi?ed cascode structures can be implemented, a trade-off between line regulation and low-voltage operation being necessary in this case. A large bandwidth of the voltage reference improves the transient behavior of the circuit, implying also a good noise rejection. Referringtothe possibilities ofimplementinga voltagereferencecircuit,two d- ferent approaches could be identi?ed: voltage-mode and current-mode topologies, being also possible to design a mixed-mode voltage reference.…

Buch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - This textbook is built upon a deliberately simplified, yet rigorous, methodological framework. Its primary objective is to enable students to develop a deep and operational understanding of the fundamental building blocks of CMOS analog integrated circuits through analytical reasoning, supported and validated by circuit simulation. The emphasis is placed not on exhaustive modelling accuracy, but on clarity, consistency, and the ability to derive meaningful results through systematic hand calculations. As a pedagogical choice, the author s approach allows the derivation of closed-form expressions for key circuit parameters, facilitates a clear understanding of the relationships between design variables, and supports the development of engineering intuition.A distinctive feature of this book is the systematic integration of analytical calculations with circuit simulation. All circuits presented throughout the text are implemented and verified using LT Spice, with consistent device parameters and supply voltages. The reader is encouraged not only to follow the theoretical derivations, but also to compare them directly with simulation results. Tosupport this learning process, all simulation files are made available to the reader. This enables immediate experimentation, encourages active engagement with the material, and facilitates independent exploration beyond the examples provided in the text. The combination of analytical rigor and hands-on simulation is intended to bridge the gap between theoretical understanding and practical circuit design.…
