A new Jitter Mitigation feature in the latest generation laser voltage probing (LVP) tool effectively removes PLL jitter from LVP waveforms [Ng Yin S, Lo W, Wilsher K. Next generation laser voltage probing. In: Proceeding, international symposium on testing and failure analysis; 2008. p. 249]. It facilitates the probing of phase-locked loop (PLL) driven circuitry inside of integrated circuits (...

Sensory pathways in the nervous system possess mechanisms for decreasing spike-timing variability ("jitter"), probably to increase acuity. Most studies of jitter reduction have focused on convergence of many subthreshold inputs. However, many neurons receive only a few active inputs at any given time, and jitter reduction under these conditions is not well understood. We examined this issue usi...

Timing jitter is a major issue in very high speed OFDM systems, which causes serious impairments that, degrades the performance of overall system. In order to reduce the effect caused by timing jitter, here in this proposal, we introduced a novel scheme that reduces the noise caused by the effect of timing jitter by using integral oversampling under different channel environments such as AWGN, ...

A new method for predicting timing jitter caused by device noise in current-mode logic (CML) frequency dividers is presented. Device noise transformation into jitter is modeled as a linear time-varying (LTV) process, as opposed to a previously published method, which models jitter generation as a linear time-invariant (LTI) process. Predictions obtained using the LTV method match jitter values ...

The effect of signal dependent jitter noise on channel capacity is investigated. Upper and lower bounds on capacity are computed numerically for channels with a mix of signal dependent jitter noise and additive white Gaussian noise. The resulting bounds allow for comparison of potential coding gain for differing amounts of jitter noise and varying code rates. The comparison provides insight int...

The transient response of a nanoinjection infrared photon detector was studied by exploring the relation between lateral charge transfer and jitter. The jitter of the device was measured to be 15 ps at room temperature. The jitter was almost independent of the pulse power, even after device saturation. Spatial maps for delay and amplitude were acquired. The carrier velocity was extracted from t...

We consider behaviors of output jitter in the simplest spiking model, the integrate-and-fire model. The full spectrum of behaviors is found: The output jitter is sensitive to the input distribution and can be a constant, diverge to infinity, or converge to zero. Exact formulas for the convergence or the divergence of output jitter are given. Our results suggest that the exponential distribution...

This paper presents an overview of the effect of synchronisation errors on MCCDMA performance in downlink communications. We distinguish two types of synchronisation errors: carrier phase errors and timing errors. We show that the MC-CDMA system is very sensitive to a carrier frequency offset or a clock frequency offset. For a maximal load, carrier phase jitter and timing jitter give rise to a ...

We evaluate the variation of inter-cell arrival times, namely jitter, as seen by a workstation. We present experimental results of actual jitter measurements on the FORE ASX200BX switch and a Pentium workstation running Linux. We analyze how the ATM network card device driver on a workstation perceives the jitter introduced by the network. We conclude from our data that the cell clumping that t...

In this paper, we investigate the influence of the carrier phase jitter of a phase-locked local oscillator on the performance of a multi-carrier code-division multipleaccess (MC-CDMA) system in a non-dispersive channel. This carrier phase jitter degrades the signal-to-noise ratio at the input of the decision device. When all users have the same power level and phase jitter spectrum, it is shown...
