SPEECH CODING ALGORITHMS Foundation and Evolution of Standardized Coders
My first contact with speech coding was in 1993 when I was a Field Application Engineer at Texas Instruments, Inc. Soon after joining the company I was assigned to design a demo prototype for the digital telephone answering device project. Initially I was in charge of hardware including circuit design and printed circuit board layout. The core of the board consisted of a microcontroller sending commands to a mixed signal processor, where all...

RF MEMS Circuit Design for Wireless Communications
This book examines the recent progress made in the emerging field of microelectromechanical systems (MEMS) technology in the context of its imminent insertion and deployment in radio frequency (RF) and microwave wireless applications. In particular, as the potential of RF MEMS to enable the implementation of sophisticated, yet low power, portable appliances that will fuel the upcoming wireless revolution gains wide recognition, it is...

Millimeter wave integrated circuits
The design and implementation of millimetre-wave (mm-wave) integrated circuits using MMIC technology are explored in this work. To make possible the widespread use of MMIC technology for mm-wave applications, high performance MMIC mm-wave transceivers must be shown to be viable for high-volume production. Low noise amplifiers (LNAs), mixers and frequency multipliers, circuit functions critical to the development of a mm-wave transceiver, are...

ESD in Silicon Integrated Circuits
In the seven years since the first edition of this book was completed, Electrostatic Discharge (ESD) phenomena in integrated circuits (IC) continues to be important as technologies shrink and the speed and size of the chips increases. The phenomena related to ESD events in semiconductor devices take place outside the realm of normal device operation. Hence, the physics governing this behavior are not typically found in general textbooks on...

Radio-Frequency and microwave communication circuits analysis design
Scientists and mathematicians of the nineteenth century laid the foundation of telecommunication and wireless technology, which has affected all facets of modern society. In 1864, James C. Maxwell put forth fundamental relations of electromagnetic fields that not only summed up the research findings of Laplace, Poisson, Faraday, Gauss, and others but also predicted the propagation of electrical signals through space. Heinrich Hertz...
