Introduction

Abstract

With the explosive growth of the communication market in the past few years, mobile personal communication devices have become very popular. The primary design effort in this area has been to lower the cost and power dissipation of these systems. Lower power dissipation directly translates into longer battery life, which is very critical for such applications. Another area of interest is to design systems that can conform to multiple standards. This gives rise to interesting challenges in terms of designing different components in this system and the design of entire system itself. Understanding the impact of electronic devices and the underlying process technology limitations on the design of components and the overall system is an important aspect of the design process. These systems are popularly known as radio frequency (RF) or infrared (IR) systems depending on the frequency of operation.
