Jitter and phase noise properties of phase-locked loops (PLL) are analyzed, identifying various forms of jitter and phase noise in PLLs. The effects of different building blocks on the jitter and phase noise performance of PLLs are demonstrated through a parallel analytical and graphical treatment of noise evolution in the phaselocked loop.

We demonstrate the folded ultrafast nonlinear interferometer (FUNI) as a 3R all-optical regenerator. Faraday rotation provides inherent polarization stabilization, and the optical fiber nonlinear medium provides ultrafast operation and switching window tunability. We demonstrate 3R regeneration of 10-Gbit/s data with 5-pJ pulse switching energy and 4-ps timing-jitter tolerance.

In a space laser communication system with few-mode fiber as the receiving terminal, influence of random angular jitter on performance cannot be ignored. Therefore, it is necessary to research coupling characteristics laser–FMF jitter. A model proposed based Laguerre–Gaussian mode. The efficiency and bit error rate (BER) are optimized by relative aperture lens. When 0.15, standard deviation 3, ...

A transmission and multiplexing strategy appropriate for voice over asynchronous transfer mode (ATM), called delayed frame queueing (DFQ), is proposed. This frame-based strategy has features in common with the synchronous transfer mode and is thus well suited to service synchronous applications such as voice, while retaining the statistical multiplexing capabilities of ATM. In particular, the D...

— This paper investigates the concept of using body bias as a design tool to optimize the timing jitter and power dissipation in single ended CMOS ring oscillators. A theoretical model for phase noise and timing jitter in ring oscillators is summarized and used as a basis for simulation of the impulse sensitivity function. Simulation results are then used to estimate timing jitter and phase noi...

The paper deals with an influence of network jitter on effective packet loss in dejitter buffer. We analyze behavior of jitter buffers with and without packet reordering capability and quantify the additional packet loss caused by packets dropped in buffer on top of the measured network packet loss. We propose substitution of packet loss parameter Ppl in ITU-T E-Model by effective packet loss P...

The influence of timing jitter on quadrature charge sampling for a direct conversion receiver has been evaluated. In contrast to voltage sampling, the charge sampling mixer integrates the signal current instead of tracking the signal voltage. The charge sampling mixer has been applied to RF direct sampling in wireless receivers. The influence of timing jitter on charge sampling has been analyse...

Jitter and shimmer are measures of the cycle-to-cycle variations of fundamental frequency and amplitude, respectively, which have been largely used for the description of pathological voice quality. Since they characterise some aspects concerning particular voices, it is a priori expected to find differences in the values of jitter and shimmer among speakers. In this paper, several types of jit...

Interactive computing systems frequently use pointing as an input modality, while also supporting other forms of input. We focus on pointing and investigate the effects of variations, i.e. jitter, in the input device latency, as well as dropouts, on 2D pointing speed and accuracy. First, we characterize the latency, latency jitter, and dropouts in several common input technologies. Then we pres...

Traditional jitter-noise analysis which mainly focuses on the clock jitter errors for impulse-sampled signals cannot accurately model the sampled-data systems that practically include nonuniform sample-and-hold effects. This paper presents a comprehensive and robust analysis of the imperfections of nonuniformly sampled-and-held signals due to clock jitter. Both the general signal to overall jit...
