Photos: Artificial eyes and airport scanners - what's hot in R&D
Photo The device uses application-specific integrated circuits to transform digital images from a camera into electrical signals in the eye that the brain uses to create a visual image. The retinal implant receives a... [21 Aug 2009]
Simulation Model of Digital Clock and Data Recovery for Strongly Disturbed Signals
White Paper All simulations were performed in the Mentor Graphic's SystemVision 4.4 environment using VHDL-AMS models of signal source, data path and recovery circuits. The paper describes VHDL-AMS simulation model... [22 Oct 2008]
Modeling of Jitter in Bang-Bang Clock and Data Recovery Circuits
White Paper In contrast to their linear counterparts, bang-bang PDs relax the speed and precision required of flipflops and other circuits in the signal path, reducing the complexity and the power dissipation. Clock... [22 Oct 2008]
Open-Loop Clock and Data Recovery Systems
White Paper CDR circuits typically use PLLs, but their complexity presents several design challenges : the input data stream is random and is usually in Non-Return-to-Zero (NRZ) data format, and little energy exists at the clock... [22 Oct 2008]
Using Application Layer Technology to Overcome the Impact of Satellite Circuit Latency on VPN Performance
White Paper It describes a client/server software solution that enables highly efficient end-to-end VPN performance over satellite circuits despite lengthy signal propagation delay. This paper explains the source of... [11 Sep 2008]

White Paper ADI) is an S&P 500 company and a global manufacturer of high-performance integrated circuits used in analog and digital signal processing applications. Analog Devices, Inc. The significant challenges... [28 Mar 2008]
Photos: Six unusual power sources
Photo Currently it is "not realistic" to try to power a mobile phone using the thermo-generators, said Peter Spies, group manager at the Fraunhofer Institute for Integrated Circuits, because the energy from the human body is... [19 Nov 2007]
Peter Cochrane's Blog: NGNs - real or imaginary?
Comment My first (personal) experience of a NGN came with the arrival of the transistor which immediately reduced equipment sizes and power consumption, and increased the number of speech circuits per pair. The next NGN involved... [02 May 2007]
Single-Chip Baseband Signal Processor for Software-Defined Radio
White Paper First, the hybrid architecture consists of reconfigurable signal processors and accelerator circuits. These accelerators are parametric circuits essential for baseband processing.... [07 Jun 2006]
VoIP primer: How it works - and what the jargon means
Comment Even the migration from analogue to digital circuits did little to change this model. Just as a web page can be broken up into 'packets', audio can be sampled with a digital signal processor (DSP),... [10 Feb 2005]
Intel gears up to put an end to PC copper
News Channels in PCI Express - a faster connection for shuttling data within a PC - can pass data at 2.5gbps, but metal channels will likely top out at 10gbps and 20gbps because of signal attenuation and other problems, said... [01 Mar 2004]
HP to unveil nanotech breakthrough
News To date, HP has demonstrated how a molecular layer can be used to connect standard computer circuits, but it has not shown off more elaborate grids complete with the intersections and signal lights that... [09 Sep 2002]
TI aims to slash PC prices with superchip
News Steve Sutton, vice president of TI's Storage Products Group, said the chip will integrate five integrated circuits (IC) for hard disk drives into a single CMOS device. It will put read-channel function with DSP (digital... [10 Mar 1999]
