Device Shot Noise and Saturation Effects on Oscillator Phase Noise

Brock, Scott E. 06 October 2006 (has links)
Oscillator phase noise is an important factor in designing radio frequency (RF) communications hardware. Phase noise directly contributes to adjacent-channel interference and an increase in bit error rate (BER). Understanding the operation of an oscillator can help with the oscillator design process. Also, the understanding of the noise processes within an oscillator can add insight to the design process, allowing an intelligent low-noise design. It will be shown that although simulation software can be helpful, the understanding of the oscillator operation is a valuable tool in the design process. Oscillator design will be discussed, and then the noise processes of the oscillator will be investigated. A new method of decomposing shot noise into in-phase and quadrature components will be discussed. The noise processes discussed for a non-saturating bipolar junction transistor (BJT) Colpitts oscillator will be extended to the case of a saturating BJT Colpitts oscillator. This new method gives insight into the design of low-noise oscillators, and provides guidelines for design of low-noise oscillators. Example oscillators will support the theory and low-noise design guidelines. It will be seen that although designing an oscillator to saturate can provide a stable output level over a wide bandwidth, the added noise production may degrade the performance of the oscillator through both a lower effective Q and restricted signal level compared to the noise. / Master of Science

Noise Description and Noise Control at the Federal, State, and Local Level

Henning, Bobby L. 01 April 1980 (has links) (PDF)
Noise, that undesirable portion of the ever-present sounds of our environment, has until the last decade, been considered as an unavoidable by-product of our rapid population growth and its accompanying mechanization. As awareness of adverse health effects from noise exposure grew, the Federal government, as protector of the public health and welfare, took the initial steps to control noise pollution. Federal legislation, beginning with the Clean Air Amendments of 1970, has been promulgated to control major offenders and to assist State and local governments in their endeavors to provide the public with an environment free from harmful noise levels. This paper first discusses sound and noise, the methods for describing and quantifying noise, and levels needed for protection. Secondly, control and abatement efforts are discussed with emphasis on legislated goals, the role of the Environmental Protection Agency, and State and local actions.
