Low Phase Noise Cmos Pll Frequency Synthesizer Design and Analysis

Title of dissertation: LOW PHASE NOISE CMOS PLL FREQUENCY SYNTHESIZER DESIGN AND ANALYSIS Xinhua He, Doctor of Philosophy, 2007 Dissertation directed by: Professor Robert Newcomb Department of Electrical and Computer Engineering The phase-locked loop (PLL) frequency synthesizer is a critical device of wireless transceivers. It works as a local oscillator (LO) for frequency translation and chann...

A dual-band frequency synthesizer for CMMB application with low phase noise

A wide-band frequency synthesizer with low phase noise is presented. The frequency tuning range is from 474 to 858 MHz which is compatible with U-band CMMB application while the S-band frequency is also included. Three VCOs with selectable sub-band are integrated on chip to cover the target frequency range. This PLL is fabricated with 0.35 m SiGe BiCMOS technology. The measured result shows tha...

Phase Noise Requirement Analysis for Millimeter-Wave Imager Frequency Synthesizer

In this paper, a nontrivial uncorrelated phase noise analysis is proposed for frequency synthesizer of a passive millimeter-wave Synthetic Aperture Interferometric Radiometer (SAIR) imager named BHU2D-U designed for concealed weapon detections on human bodies with high imaging rates. This synthesizer provides local oscillators both for millimeter-wave front-ends and intermediate frequency IQ de...

Monolithic Low Phase Noise Oscillators for Moderate Frequency Applications

Low noise oscillators are critical building blocks in a wide range of commercial electronics. Increased levels of integration have created a strong need for integrated oscillator solutions despite generally inferior noise performance. The development of non-linear noise models that can accurately and efficiently predict noise in ring oscillators aids designers in optimizing noise performance in...
