The trend in design and manufacturing of very large-scale integrated (VLSI) circuits is towards smaller devices on increasing wafer dimensions. VLSI is the inter-disciplinary science of the process of creating an integrated circuit (IC) by combining thousands of transistors into a single chip. VLSI design can reduce the area of the circuit, making it less expensive and requiring less power.The book gives an understanding of the underlying principles of the subject. It not only focuses on circuit design process obeying VLSI rules but also on technological aspects of prototyping and fabrication. All the clocking processes, interconnects, and circuits of CMOS are explained in this book in an understandable format. The book provides contents on VLSI Physical Design Automation, Design of VLSI Devices and also its Impact on Physical Design.The book is intended as a reference book for senior undergraduate, first-year post graduate students, researchers as well as academicians in VLSI design, electronics & electrical engineering, and materials science. The basics and applications of VLSI design from STA, PDA and VLSI Testing along with FPGA based Prototyping are covered in a comprehensive manner.The latest technology used in VLSI design is discussed along with the available tools for FPGA prototyping as well as ASIC design. Each unit contains technical questions with solutions at the end.Technical topics discussed in the book include: * Static Timing Analysis* CMOS Layout and Design rules* Physical Design Automation* Testing of VLSI Circuits* Software tools for Frontend and Backend design.

The current cutting-edge VLSI circuit design technologies provide end-users with many applications, increased processing power and improved cost effectiveness.

The growth of Electronic products becomes more complex due to a major requirement of high reliability, high speed and low cost. In today¿s world, reliability becomes a great need of any electronic equipment for active as well as passive components such as a temperature sensor. Failure prediction is the major constraints to predict the remaining useful life of the component in order to anticipate the costly failures or system unavailability. In the modern competitive market, low cost and high performance are the key factors to attract the customers towards their products. Growing system complexity demands robust control to reduce system control and to reduce the successive failures. Reliability prediction of passive components especially temperature sensor is of great concern as these are required in almost every system. As these components are mounted on a board to form a complete system, the probability of damage is increased, as the different components have different characteristics and different operating conditions. So artificial intelligence techniques are used which adopt knowledge of failure mechanism of an individual part of the system and check the health condition of it.

From daily life applications to military applications and from toys to satellites, the use of electronic components is in extensive. Due to rapid evolution of electronics device technology towards low cost and high performance, the electronics products become more complex, higher in density and speed, and lighter for easy portability. Reliability prediction of the electronic components used in industrial safety systems requires high accuracy and compatibility with the working environment. The user can replace faulty component with the accurate one, and system will be saved from complete shutdown. Using low-cost materials, carbon, and potash alum, a new solid composite electrolyte system was fabricated and characterized using various techniques. An Arrhenius behavior was reported when the temperature dependence of conductivity was analyzed. The synthesized solid composite electrolyte exhibited excellent humidity sensing behavior. An expert system was modeled using artificial intelligence techniques and failure of the sensor was predicted using artificial neural networks (ANN), fuzzy logic (FIS) an adaptive neuro-fuzzy inference system (ANFIS).

The text discusses advanced concepts of nanotechnology and its applications in the fields of medicine, agriculture and renewable energy. It will be an ideal reference text for senior undergraduate and graduate students in the field of electrical engineering, electronics engineering, nanotechnology and nanoscience.
