Radio-Frequency Digital-to-Analog Converters

Chapter 1

Introduction

Abstract

The reasons for writing this book are outlined in this introductory chapter. The conventional radio has too many components, which are bulky, costly, and consume too much power. Further, the technology used tends not to be aligned with the deep nanoscale CMOS used by digital processors. Hence, a new digitally intensive wideband in-phase/quadrature transmitter architecture is proposed to remove the aforementioned handicaps and to promote further progress. The chapter then gives necessary background to understand the system-level aspects of wireless transmitters and qualitatively compares the new architecture with prior art.
