Delta-sigma modulation in fractional-N frequency synthesis
TL;DR: In this article, a delta-sigma (Delta-Sigma) modulation and fractional-N frequency division technique for indirect digital frequency synthesis using a phase-locked loop (PLL) is described.

A simplified continuous phase modulator technique
T.A.D. Riley,M.A. Copeland +1 more
TL;DR: A low cost GMSK (Gaussian minimum shift keying) modulation technique is presented, suitable for any continuous phase constant envelope modulation with discriminator, differential or coherent detection in the targeted receiver.

Direct digital synthesizer for reference frequency generation
TL;DR: In this paper, a multi-modulus divider, a numerically controlled oscillator and a programmable delay generator are used to synthesize a direct digital frequency synthesizer with phase-dithering noise induced by input into the accumulator of an increment generated from a pseudo-random noise generator.
Dissertation
Techniques for high data rate modulation and low power operation of fractional-N frequency synthesizers
TL;DR: A digital compensation method is described that allows fractional-N frequency synthesizers to be directly modulated at high data rates while simultaneously achieving good noise performance and good performance, low power operation, and high levels of integration are achieved with the approach.
Proceedings ArticleDOI
Spur reduction techniques in direct digital synthesizers
TL;DR: Spur reduction techniques used in direct digital synthesizers (DDSs) or numerically controlled oscillators (NCOs) are reviewed and spur reduction techniques which reduce spurs by destroying the coherence of the aliasing process are discussed.

Charge-Pump Phase-Lock Loops
TL;DR: This paper analyzes typical charge-pump circuits, identifies salient features, and provides equations and graphs for the design engineer.
Journal ArticleDOI
A digital frequency synthesizer
TL;DR: The digital technique lends itself to the production of phase coherent or phase controlled sinusoids because of the indexing arrangement used and finer frequency steps than the READ-ONLY memory allows are available by expanding theindexing register at no increase in inaccuracy.

A survey of digital phase-locked loops
William C. Lindsey,Chak Chie +1 more
TL;DR: A systematic survey of the theoretical/experimental work accomplished in the area of digital phase-locked loops (DPLL's) during the period of 1960 to 1980, thereby offering speedy access to the techniques and hardware developments which have been presented in a scattered literature.
Journal ArticleDOI
Phase-locked loops
TL;DR: An attempt to systematically outline the work done in the area of phase-locked loops which are now used in modern communication system design is presented.
