CMOS RFIC Design Principles

Chapter 1: Introduction

The computer will become the hub of a vast network of remote data stations and information banks feeding into the machine at a transmission rate of a billion or more bits of information a second. Eventually, a global communications network handling voice, data and facsimile will instantly link man to machine or machine to machine by land, air, underwater, and space circuits.

1.1 Historical Perspective and Background

1.1.1 A (Very) Brief History [1]

1.1.1.1 Portable Radio and Wireless Systems

During the Christmas season of 1906, radio operators at sea heard from their radio receivers not the usual Morse code [2] transmissions, but rather the sounds of Christmas music and a violin solo. This ground-breaking audio transmission scheme (and the violin solo) was the creation of Reginald Fessenden, a Canadian engineer who at one time had worked with Thomas Edison [2]. So began a century of rapid advances in radio and wireless transmission of voice information. A century ago, radio transmissions were based on a single transmitting and receiving architecture using "spark gap transmitters" and "coherer receivers." During the next 50 years, the codevelopment of vacuum tubes and various modulation schemes and system architectures vastly improved the efficiency and performance of radio communication links. The invention of the transistor as a replacement for vacuum tubes ushered in another 50 years of communication system development, not only in terms of performance but also in terms of the system's physical size, weight, and battery consumption.
