Clock and data recovery (CDR) circuits are key electronic components in future optical broadband communication systems. In this paper, we present a 40-Gb/s integrated CDR circuit applying a phase-locked loop technique. The IC has been fabricated in a 50-GHz f T self-aligned double-polysilicon bipolar technology using only production-like process steps. The achieved data rate is a record value f...

We present a new approach to minimizing of energy consumption by addressing battery management techniques that exploit the charge recovery effect inherent to many secondary storage batteries. We review results that pertain to the capacity of a battery and its dependence on the intensity of the discharge current. The phenomena of charge recovery that takes place under bursty or pulsed discharge ...

The jobless recoveries in the aftermath of the 1991 and 2001 recessions have puzzled many. Most explanations have focused on structural change. In this paper, I investigate the quantitative contribution of a cyclical mechanism towards generating jobless recoveries. Extending the model by Hansen and Sargent (1988), I calibrate and compute a dynamic stochastic general equilibrium model of heterog...

Disasters have the potential to cripple a country and those countries that are particularly susceptible to disasters must have adequate disaster recovery plans in place to ensure that the country can return to normalcy as soon as possible after the disaster. These plans will involve a number of autonomous entities that need to be able to communicate and coordinate their activities effectively. ...

Bang-Bang clock and data recovery (BBCDR) circuits are hard nonlinear systems due to the nonlinearity introduced by the binary phase detector (BPD). The specification of the CDR frequency response is determined by jitter tolerance and jitter transfer. In this paper, jitter transfer and jitter tolerance of the second-order BBCDR are characterized by formulating the time domain waveforms. As a re...

Sufficient number of linear and noisy measurements for exact and approximate sparsity pattern/support set recovery in the high dimensional setting is derived. Although this problem as been addressed in the recent literature, there is still considerable gaps between those results and the exact limits of the perfect support set recovery. To reduce this gap, in this paper, the sufficient con...

Disaster recovery planning for organizations is fundamental and often urgent. Planning supports the firm’s ability to recover the core business functionality of its software, data, and systems after the occurrence of a natural or man-made disaster. Organizations must take steps to protect their software, systems and data backups from natural disasters, power outages, and even terrorist attacks....

Storage clouds use economies of scale to host data for diverse enterprises. However, enterprises differ in the requirements for their data. In this work, we investigate the problem of resiliency or disaster recovery (DR) planning in a storage cloud. The resiliency requirements vary greatly between different enterprises and also between different datasets for the same enterprise. We present in t...

REQUIRED) The concept of IT disaster recovery planning is receiving an increasing amount of attention from IT practitioners and business managers due to its importance in averting disasters and ensuring the continuity of organizations. Surprisingly, little research has been aimed at providing a comprehensive definition of this topic. Thus, this manuscript describes the process by which conceptu...

ct In burst-mode data transmission used in GSM and IS2. INITIAL PARAMETER ESTIMATIONS FOR BURST Abstra 136, rapid acquisition of the symbol timing and the carrier phase from the observation of a short signal-segment is essential. Feedforward timing recovery is well suited for such transmissions due to its rapid acquisition characteristics. For personal mobile communications where low complexity...
