Description
IET PUBLISHING Digitally Enhanced Mixed Signal Systems by Chadi Jabbour
Digitally enhanced analog and mixed signal techniques are increasingly important to current and future circuit and system design. This book discusses how digital enhancement can be used to address key challenges relevant to analog components in terms of shrinking CMOS technology, increasing user demand for higher flexibility and data traffic in communications networks, and the drive to reduce power consumption.The book opens with an introduction to the main trends in current digitally enhanced systems, emphasising the impact of shrinking technology, and provides an overview of the principles of non-linear models. Later chapters cover pre-distortion and post-distortion techniques, analog-to-digital and digital-to-analog converters, clock generation, fixed-point refinement and adaptive filtering. Key themes of the book are the implementation approaches common between digital enhancement techniques and the trade-offs between complexity and performance for digitally enhanced devices and circuits. The book will be of particular interest to academic researchers and engineers working in analog and mixed signal circuit and system design.
