ABSTRACT
Six sigma is best described as a journey-a journey for business professionals who are truly committed to improve productivity and profitability. Six sigma isnâ„¢t theoretical; its an active, hands-on practice that gets results. In short you donâ„¢t contemplate six sigma; you do it. And doing it has proven to be the Fast track to vastly improve the bottom line.
The six sigma story began in 1980â„¢s at Motorola, where it has first developed and proven. This is where six sigma took off. Mikel Harry, P ....etc

SIX SIGMA -Quality Improvement Program

ABSTRACT:
Six Sigma is a smarter way to manage business or department. It is a vision of quality that equates with only 3.4 defects for million opportunities for each product or service transactions. Strives for perfection.
We believe that defects free product can be in any organization implementing six sigma. In this paper, we presented an overview of the process which explains how six sigma increase the overall quality improvement task into a series of project manageme ....etc

Six Sigma is a methodology

Six Sigma is a methodology to manage process variations that cause defects, defined as unacceptable deviation from the mean or target; and to systematically work towards managing variation to eliminate those defects.

The objective of Six Sigma is to deliver high performance, reliability, and value to the end customer. It was pioneered by Bill Smith at Motorola in 1986 and was originally defined as a metric for measuring defects and improving quality; and a methodology ....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

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
