With the development of low power mobile wireless personal communication and the improvement of performance of CMOS technology

to implement a RF front end of a wireless communication system using CMOS technology is not only neceessary but also feasible.In this paper

special issues to implement the RF integrated circuits are discussed.Firstly

a variety of transceiver architectures are reviewed in comparison of their characteristics and kernel issues that should be addressed in transceiver design.Secondly

important building blocks of CMOS RF front end

including low noise amplifier

mixer

frequency synthesizer and power amplifier

are discussed.The core subject of such building blocks such as figure of merit

possible circuit schematics and others are presented.Thirdly

the possibilities and methods to integrate the inductor and capacitor in the RF band are figured out in this paper.And

finally a perspective for the development of CMOS RF integrated circuits are dressed out.
