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...

In recent times a remarkable breakthrough has occurred in the field of optical frequency measurement and synthesis. For the first time it is now possible to generate arbitrary waveform light pulses, perform accurate optical frequency synthesis and accurately measure the frequency of optical frequency signals. These long dreamed of possibilities have been delivered because of the existence of tw...

A frequency synthesiser architecture for millimetre-wave applications is proposed. The architecture is based on a triple-push oscillator, which functions both as a divider and oscillator. Thus, the proposed architecture eliminates the need for injection locked frequency dividers that are the main contributors to the limited tuning capability of millimetre-wave phase-locked loops. Since the prop...

The Flying-Adder frequency synthesis architecture is a novel approach of generating frequencies on chip. Since its invention, it has been used in many commercial products to cope with difficult frequency generation challenges. Along the course of this architecture’s evolution, various circuitand system-level problems have been resolved. In this paper, one remaining problem related to circuit im...

A frequency synthesis is a combination of electrical system elements that results in the generation of one or many frequencies from one or a few reference sources. The fine frequency resolution, low spurious signals, accuracy and stability are most important for these devices. The frequency synthesizers are an essential part of any modern communication system. They generate clock and oscillator...

This paper presents a low distortion signal generator with a frequency range from 0 to 10 kHz using the direct digital synthesis (DDS) method for ADC characterization. The results show that the maximum distortion in the whole frequency range is -80.37 dB, the frequency resolution is 1.421 nHz (with a 48-bits DDS chip), the stability in frequency is 25 μHz/Hz and the amplitude stability is 13 μV/V.
