A companion analysis of clock jitter and phase noise of single-ended and differential ring oscillators is presented. The impulse sensitivity functions are used to derive expressions for the jitter and phase noise of ring oscillators. The effect of the number of stages, power dissipation, frequency of oscillation, and shortchannel effects on the jitter and phase noise of ring oscillators is anal...

Data communication rates have increased tremendously over the past 5 years in order to accommodate the exponential growth in data transmission. It is common today to have serial data streams in storage area networks that exceed 2 Gb/s and it is expected that high-speed serial signals in backplanes will reach 6.25 Gb/s in 2003. Consequently, the minimum pulse width of these serial data streams h...

Phase noise and jitter are two related quantities associated with a noisy oscillator. Phase noise is a frequency-domain view of the noise spectrum around the oscillator signal, while jitter is a timedomain measure of the timing accuracy of the oscillator period. This paper discusses the relationship between phase noise and jitter in free-running oscillators. The reader is referred to three othe...

We added simulated vertical viewpoint jitter and oscillation to radial optic flow displays designed to induce forward vection. Display jitter and oscillation were both found to increase vection strength during, and reduce motion aftereffects (MAE) following, exposure to the optic flow (compared to no-jitter controls). Display jitter, which induced the strongest vection of all the conditions tes...

BACKGROUND Single-fiber electromyography (SFEMG) has been suggested as a quantitative method for supporting chronic partial denervation in amyotrophic lateral sclerosis (ALS) by the revised EI Escorial criteria. Although concentric needle (CN) electrodes have been used to assess jitter in myasthenia gravis patients and healthy controls, there are few reports using CN electrodes to assess motor ...

The e€ects of g-jitter on heat and mass transfer in underpressurized, annular liquid jets are analyzed numerically as a function of the amplitude and frequency of the gravitational modulation by means of a mapping technique that transforms the timedependent geometry of these jets into a unit square and a conservative ®nite di€erence method. It is shown that the pressure coecient, gas concentra...

This dissertation addresses the problem of displaying live continuous media (e.g., digital audio and video) with low latency in the presence of delay jitter, where delay jitter is defined as variation in processing and transmission delay. Display in the presence of delay jitter requires a tradeoff between two goals: displaying frames with low latency and displaying every frame. Applications mus...

Designing leading-edge systems (e.g., communications systems) requires knowledge about the technological limits. Jitter is the limiting effect in wideband ADCs with a digitization bandwidth between 1 MHz and 1 GHz. The effects of aperture jitter and clock jitter have been investigated previously. However, some very important aspects are still missing, in particular investigations on the spectra...

The number of Internet users is increasing quickly with the transmission of voice over IP. Therefore provision of fast transmission without jitter and delay is the fundamental aspect of voice communication. This study evaluates the performance of SCTP and TCP in transmission of voice packets. Generally, when packets are arrived at destination, these are probably affected by jitter. Many researc...
