Introduction

The proliferation of wireless products over past few years has been rapidly increasing. New wireless standards such as GPRS and HSCSD have brought new challenges to wireless transceiver design. One pivotal component of transceiver is frequency synthesizer.

Two major requirements in mobile applications are efficient utilization of frequency spectrum by narrowing the channel spacing and fast switching for high data rates. This can be achieved by using fractional- N PLL architecture. They are capable of synthesizing frequencies ....etc

Introduction
The sigma delta conversion technique has been in existencefor many years, but recent technological advances now makethe devices practical and their use is becoming widespread.The converters have found homes in such applications ascommunications systems, consumer and professional audio,industrial weight scales, and precision measurement devices.The key feature of these converters is that they are the onlylow cost conversion method which provides both highdynamic range and flexibility in converting low bandwidth inputsignals ....etc

ABSTRACT
Wide band Sigma-Delta PLL modulator is based on PLL fractional N synthesis techniques along with Sigma-Delta modulation to randomize fractional N spurs. A modified Sigma-Delta function allows for suppression of Sigma-Delta noise at low frequencies & hence allows wider bandwidth. This is achieved using a fractional-N PLL architecture. They are capable of synthesizing frequencies at channel spacings less than the reference frequency. This helps to increase the reference frequency & hence reduces PL ....etc
